Hi
I’ve set up a L2TP-server on my main router ( static wan ip ). A second router on a remote location, behind NAT( which I can’t control )and with dynamic wan ip dials in to my main router as a L2TP client, and it works perfect, I’m running a EoIP tunnel over the L2PT-connection.
L2TP server.: 172.16.2.1 L2TP client.: 172.16.2.2
I can ping 172.16.2.2 using the ping tool on my main router, but I can’t ping 172.16.2.2 from my PC which has full access to the main router, and I guess this is why I also can’t connect from Winbox on my main PC to 172.16.2.2 ?
Do I have to add some routing, or is there something else that I have to be aware off ?
Anything that might point me in the right direction will be highly appreciated - thank you.
