split tunneling? #100

Closed opnslm closed 8 months ago

opnslm commented 8 months ago

So i need to tunnel dsvpn over tls. I set up stunnel(it is a tls tunneler to who dont know) everything works fine i can comminucate with the vps. But if i run dsvpn under stunnel it tries to tunnel all the traffic and interrupts the stunnel traffic. Is there a split tunneling method(i am on linuz btw) maybe like while the vpn is setting up the tun interface change some routing settings or not tunneling an ip address at all. thank you!

There's an undocumented option to prevent dsvpn from setting routes. Add -DNO_DEFAULT_ROUTES to the OPTFLAGS environment variable.

It will then create the tun interface for you but you'll have to set up all th routes yourself.

What are the exact commands you need to type for your use case, I don't know. You probably know Linux way better than I do :)

How can i use the environment variable method do i put it in makefile. I don't know c that much. Where can i find the routes that is being added while the tun interface set. Thanks for the compliment;)

okay i found the way to disable route it is in 98 issue(https://github.com/jedisct1/dsvpn/issues/98) and the routes for tun interface i think is on line 485 in os.c am i correct
