Can't play CSS though an Adhoc

[alidanis5]

Hi all, first post, will probably sound noobish.

I've made a server for CSS, but every time I try to run the server through an Adhoc, I keep getting Steam connection errors

I've set sv_lan to 1 but the problem still occurs.

Any help would be great

sv_lan 1 means lan is on, you want sv_lan 0 for internet right?
