Dear all,

I need to setup the mikrotik router in router mode and that will forward the conection from wireless client
to a third-party hotspot server for authenication. If I enable NAT in mikrotik, the wireless clients can redirect
to third-party hotspot system login page, but if I disable NAT, cannot load the login page. I need to setup
without NAT because our hotpsot server will make its as one client(same source IP) and except first
connected machine, even there are many client connected.

How can I setup the environment in Mikrotik for my requirement? My ideal option is use router mode but not
hotspot mode in Mikrotik. Actually, I need the hotspot server can get the actual IP address through the wireless
client and not the router IP for authenication.

Thx
Rgds,
Jeffrey

Hi, You can use bridge. Bridge wireless & WAN interface.

The hotspot system should have a static route for the IP segment your systems are on.
I guess your hotspot system has a default gateway and since your systems are on a different segment the hotspot system sends the returning packets towards it's default gateway.
If you configure 1 static route for the IP segment your clients use, and point that towards the 'outside' address of your router, then you're good to go.
