"something is missing/not good enough on the mikrotik device and I want to add/replace it" I think that's all to it. They they seem to keep adding extras to ROS to allure to more potential customers. Until it doesn't compromise base functionality or security, I don't thing there's harm in...

Hi, gurus :) . Since ROS still does not support tls-auth for OpenVPN (so many years... :?), I've been trying to find a workaround with OpenVPN client (giggio/openvpn-arm) running within the ROS container. However, no success. The client within container successfully connects to VPN server, I can re...

Add your tun/taps as variables for your container. I tested with Zerotier in an Alpine Linux image and it works perfectly:

ZTTUNTAP.png

Nice!

kobuki

Could you allow systemd to work inside container?

NO!

That sounds good! How will it be supported?

/dev/net/tun device now is available for container use

I'll try as soon as I can after work. Is net_admin capability available along with tun?

kobuki

tun/tap support will be added in next release. Anything else to consider adding before stable release? Could you allow systemd to work inside container? It's practically never needed (but not impossible) for a container. A Docker container is not a VM nor an LXC container that provides full OS virt...

kobuki

There will always be some changes or requirement for configuration. Creating a TUN or TAP is not enough, you also need to configure how it is to be connected to the remainder of the network. Even when you run OpenVPN natively on a Linux box you will need to do that. So it is nothing special. We're ...

kobuki

Sure it can! I have written software that uses TUN/TAP myself. It requires privileges to create a TUN or TAP interface but once you have done that and opened it you can pass it along as an fd that can be used by less-privileged code. So it would be possible to arrange that a container config can cr...

kobuki

OpenVPN is open source so it can be modified to adapt to a different situation. Are you being sarcastic? But anyway, no, it can't. Using the tuntap kernel module, tun/tap devices, network admin functions, etc. is in its very foundation. And anyway, who would have the capability to make such changes...

kobuki

Maybe you can add such network config capability to the RouterOS container config/setup menus? It could mean certain software (after adaptation) could use the network devices previously setup, without the container having permission to do it by itself. For one, OpenVPN requires this cap after start...

kobuki

Will it be possible to add capabilities to containers? For instance, cap NET_ADMIN is required to create/use TUN/TAP virtual network devices for various functions. OpenVPN or other VPN solutions, like OpenConnect requires this functionality.

kobuki

As soon as the container feature is stable, an OpenVPN container, as the ROS implementation is a fraction of the upstream. I could finally stop depending on another device for my OVPN needs.

kobuki

There are no port mappings in this config panel, will they be added later?

kobuki

All base OS images need a command to run, otherwise they're just a bunch of files extracted to the overlay FS. It would be nice to be able to spec the command to be run even for these images in ROS, like for standard docker tools.

Mikrotik support has a response to this issue: The warning will appear when you have some untagged port automatically added to the VLAN group. This happens when the port has set "pvid" and then in "/interface bridge vlan" table you create an entry with multiple VLANs, which inclu...

kobuki

If /interface bridge vlan print does not show any ports in the CURRENT-UNTAGGED column when that error is displayed it could be a bug. wlan interfaces themselves have options for VLAN tagging so it may be a historic artefact.

kobuki

It isn't the CAP configuration, it relates to having untagged= entries under /interface bridge vlan on rows which specify more than a single value for vlan-ids= .

As I stated tdw, its not a simple matter its the fact that the OP does not understand Bridge vlan filtering and thus giving him the config answer is actually not helpful as he will now not read the link nor really learn anything.

kobuki

OK, additional info: the warning only appears when there are active CAP wlan interfaces dynamically added to the bridge. If I disable CAP and thus the dynamic ports, the warning disappears. I admit that I'm not very experienced with CAP, so the issue might lie somewhere in that config. Although I on...

kobuki

I'm surprised no one could answer this... Anyway, let me put it another way: on a CRS326, can I do anything in the bridge and/or VLAN/filtering that disables HW offload? Will I need to do any kind of filtering in the switch menu?

kobuki

I want to achieve a seemingly simple goal: "split" ingress traffic to 2 VLANs received on an ethernet interface, using a CRS326 or similar 24-port switch. I have an ISP provided gateway that offers IPTV streams in some VPCs (not important) and besides this traffic, there's a PPPoE connecti...

kobuki

FWIW, I've set up a nightly restart of the affected router and it offers a workaround, as the issue hasn't repeated yet since then. I's not ideal and not a real solution but causes no problems at the moment. I'm still hoping for a backport of the fix in the LTS series.

Not all of it, you should keep vlan20 and related L3 setup ... And make sure you firewall VLAN20 from the rest of LANs (and WAN) on your main router.

kobuki

OK, I changed the bridge/port config per suggestions, but it still doesn't work. By that I mean not a single ping is working between the 2 devices with this setup on neither VLAN. With torch or packet capture it's obvious that the packets are not tagged properly so they don't flow in the right VLAN....

kobuki

Yup, leave pvid set to 1 or whichever vid you're not going to use. How things work: if a port has pvid set, it will add VLAN tag to any untagged packets on ingress. And natural configuration would be to have same port set as untagged member of same VLAN ... so that VLAN tags get stripped on egress....

kobuki

1st rule: don't use pvid on bridge, rather explicitly configure vlan interface with appropriate vid (as you have it later in the config) 2nd rule: don't ever use pvid on trunk interfaces, run them all tagged (right now you have configuration mismatch... ether1 n CRS and ether2 on RB have pvid=10 se...

I want to connect the VLANs between the devices and provide DHCP on VLAN 10, while VLAN 20 is an adminis...

kobuki

I already mentioned two of those. Support is in mainline for ages. Both stable, widely used. As for security, both can work unprivileged (no root access at all). A chroot is not a solution. But it's up to MT anyway and I'm not really keeping my hopes up in either subject.

kobuki

I know what MR is and I used to use and test it. But it's not supported well and I have no idea what technology it uses. Seems left in ROS as a feature but it's effectively abandoned.

kobuki

I don't recall any of the device series released in the last couple of years actively supporting or advertising any kind of virtualization (not talking about x86 solutions here). Only one should be supported, if ever, not 2 or more. That wouldn't make sense. If the technology changes, so be it, but ...

kobuki

VIrtualization is a ubiquitous technology nowadays. Almost all x86 and many ARM platforms (and more) are capable of running it. Kernel/cgroup based technologies (eg. Docker, LXC) are practically available anywhere where a Linux kernel is running. It's not rudimentary, it's rock solid (when properly ...

If at least we had a robust implementation of any virtualization tech in ROS for the lower-end devices, we would be able to add an image with a fully working OVPN implementation.

So ether 5 is a TRUNK port and not an access port?????

Yes.

/interface bridge vlan add bridge=bridge-lan tagged=bridge-lan,ether5 vlan-ids=20

This one solved it, thanks! I know the PVIDs are redundant but they do practically nothing in this setup, so it doesn't hurt either. ROS defaults to PVID 1 and I tend to change it from 1 to one of my VLAN IDs.

From the full config you can see that ether5 is added to bridge-lan, and that is the interface connected to a trunk port on a switch with vlan 20 where only tagged packets travel.

Well, I solved this, kind of. /ip address add address=88.x.x.177 interface=ether2 network=78.y.y.132 /ip route add gateway=78.y.y.132 ROS automatically adds a host route for 78.y.y.132 (main ip of the host machine, outside of the routed /29 subnet) on ether2 and I can use it as gateway for the /29 e...

kobuki

Well, I have tried your suggestions, but neither of them is working on RouterOS. I can't make it work, whatever I try. I even enabled proxy arp on the host so the upstream gw appears as directly connected IP, to no avail. If the ROS doesn't have an IP from the same subnet as the gateway, it doesn't ...

I'm trying to create a simple config at a datacenter where I am allocated a single "main" IP with a default GW on the same subnet. All is fine. Then I requested for an additional subnet which is statically routed to this main IP. It's from a different, arbitrary subnet. This setup is virtu...

Well, I actually solved it at last. I don't know what the problem was, I rebuilt the IPSEC config from scratch and poof, it started working. No config difference compared to what I've shown earlier, that I know of. Weird.

kobuki

Oops, my mis-read, sorry. I'm used to mis-configuring it myself where I put the connect-to IP in instead of the remote-LAN IP, glossed over your opening statement, sorry. Do you have a regular client connection that works with these settings? To me, the MT settings look correct and I'd be inclined ...

You need your /ip firewall nat rule (the bypass rule) to match the local and remote private networks. So, if the local side is 192.168.1.0/24 and the remote side is 192.168.2.0/24, your NAT bypass rule would be as follows: /ip firewall nat add chain=srcnat src-address=192.168.1.0/24 dst-address=192...

As I've already said, I was comparing the two while trying to decide. No NAT figures there, only routred/bridged config with and without conntrack, which is not the same. Actually, far from it. The 450G is capable of a NAT througput at around 200 Mbps (based on others and on my own experience), whil...

kobuki

Well, i guess so. Compared to the 450G, how are NAT throughput figures? Can the 2011 top the 450G's max througput of about 200 Mbps? This in an information I'm unable to find. I won't actually need more than that, of course, just wondering.

kobuki

Yeah, comparing the throughput figures, I thought so too. No queues planned so far, however, I'm concerned about the amount of ram. 2011 has 64M, while the 450G has 256M. Although no heavily loaded servers inside with thousands of connections, so it might not be an issue.

Thanks for the replies. I'm using Zabbix for the moment, and it doesn't influence the SNMP readings at all (CPU load or anything else). I'm suspecting RouterOS is misbehaving at certain periods. I might need to forget the built-in graphing completely if it's so unreliable.

I've employed an RB450G in a datacenter recently, and experiencing strange 100% CPU usage spikes on the CPU graph.
