Hi, can you help to hook network part of engine, i have 3 ISP setup on my server and only one can be used at the same time because all pakets go throught default gw, its about UDP implementation in engine - i found a solution how fix it, but i didnt know what functions to hook. The idea is to use IP_PKTINFO, recvmsg, sendmsg so i can send packets to that interface wich packet came from

thanks.

PS: sorry for bad english

Can't you just use the -ip parameter to startup the srcds with the correct network interface IP ? Or add a route.. ?

He wants to use Three IP addresses with his server, which would be cool provided they were all different ranges.

[berni]

What about setting the socket to 0.0.0.0 ?

In the worst case you can hook the system networking libraries used by HL2, which would be very platform specific.

i want to use 3 ip at same time, if i use 0.0.0.0 all UPD packets are send to default gateway, but not to that gateway from wich packet came

i already hooked creating socket so i can turn on IP_PKTINFO, but its hard to find correct loop where packets recv and send to clients

_Z14NET_OpenSocketPKcRib in engine

the only way for me now is to buy additional router or another pc - to take role of router
by router i can mark packects so it will know wich packet came from
but on local pc i cant do that even if i mark incoming packet - outgoing packet are new ones in nf_conntrack and not the same, on tcp connections all ok, but its only rcon

sorry my bad english couldnt explain as it is

You could always cheat with iptables, forwarding traffic from one NIC to the other, and vice versa. This worked for me in the past, but became quite troublesome because half the player base was attached to one range, and the other on the other range.

That, and the server was no longer listed on the master server after I swapped my main range over. Just another way of going about this, the iptables way does have its drawbacks.
