Thanks For Reply.
I done it, & can ping each other network already, but the problem now is i cant see game for each other network.
Mean if i create game at side A (DOTA), side B cant see my game at all.
I tried use PFsense to do VPN through IPsec, also the same problem happened.
Zeroshell have any way to allow UDP broadcast forwarding???
(as i know DOTA-warcraftIII need to use UDP broadcast)
Thank again for your attention^^
