Any help or idea given is welcome
I have two separate internet connection assume one named primary and the other secondary. The main internet traffic is being routed through the primary connection but port 1723 for vpn service is not open from my provider. I want to use the secondary internet connection just for vpn services. My internal network is being natted behind a Mikrotik router. The problem is as follows:
When I use as gateway for the internet traffic the gateway of the primary internet router (route 0.0.0.0/0 through 10.74.4.1) then the vpn service cant be established because any call for vpn through the secondary internet connection is being tried to be routed back thought the primary internet connection where the port 1723 is locked.
On the other side when I use as gateway for the internet traffic the gateway of the secondary internet router (route 0.0.0.0/0 through 192.168.10.254) then the vpn service is available and working very well but internet traffic is being routed through the secondary internet connection despite of the primary.
If anybody has an idea of solving this issue I ll be very grateful. Thanks in advance.
Use mangle rules in the Firewall to mark packets for port 1723 and GRE, then use routing tables to setup a specific default route for the marked packets.
Could you give me some more hints? I tried a lot of things all by the book but i havent achieved to set up things working properly. Thanks in advance
