我有一个client that needs to create a site to site pptp connection from a w2k3 server with ISA server installed through my wireless network to a server on a public IP on the internet.
I tried different types of pptp connections. From the different MT's, from a normal pc with client pptp all works fine. I have pptp and gre helpers on, connection tracking on, firewall rules to allow 1732 port and gre - protocol.
When I put the server directly on my network behind the adsl modem bypassing any mikrotik system it works 100%.
What is wrong and how can I fix this?
