vpn traffic type

[talis]

Hello.

My friend and I have a vpn between our machines. Recentely we tried to play games via it. Those games that have lan server discovery feature do not find my friend's server when its running - looks like there is some specific type of traffic used for that (e.g. broadcasting packages). "Connect to ip" option works perfectly if there is one. We tried both ethernet and ip tunneling modes (tun/tap). We also tried to disable firewalls for vpn connections - didn't help.

I though maybe you guys know what's going on? How do these things work and why they don't work with vpn? Can it be a problem in normal use (not for gaming) and how do you solve/bypass it if it can?

Thanks in advance.

P. S. Sorry about the topic name - I didn't know how to name this question better.

take a look at
topic7319.html
to see if that solves your (not really VPN specific) problem.

janjust, thaks a lot you for your reply! That thing should work. So, it's not OpenVPN problem, it's about Windows design flaw (stupidity?) and there should not be such problems on Unix hosts, right?

[janjust]

well, you can make the same programming mistake on Unix/Linux
it has mostly to do with how 'lan server discovery' is implemented and , of course, how it is tested; it is obvious that 'lan server discovery' is not tested well in VPN setups.

janjust, thanks again

Good luck.
