Simple nat problem.. SOLVED

Please disregard my previous thread.

I have 8 multiple external IPs.
I have 2 servers
I run multiple instances of the game on the same server just using different ports.
I'd like to map the same port on each of the WAN ips to to a different port on the server eg

GAMESERVER INSTANCE1 88.174.120.45:27960 –--> 10.0.0.2:27960

GAMESERVER INSTANCE2 88.174.120.46:27960 ----> 10.0.0.2:27970

GAMESERVER INSTANCE3 88.174.120.47:27960 ----> 10.0.0.2:27980

GAMESERVER INSTANCE4 88.174.120.48:27960 ----> 10.0.0.2:27990

GAMESERVER INSTANCE5 88.174.120.49:27960 ----> 10.0.0.3:27960

GAMESERVER INSTANCE6 88.174.120.50:27960 ----> 10.0.0.3:27970

GAMESERVER INSTANCE7 88.174.120.51:27960 ----> 10.0.0.3:27980

GAMESERVER INSTANCE8 88.174.120.52:27960 ----> 10.0.0.3:27990

Standard nat doesnt work for any of the VIPs, the wan interface nat is fine. im not sure what kind of VIPs i should have added them as.....

Subnet mask for the externals are 255.255.248.0 which if im correct is a /21 block, but my ISP claims its a /19??

Also would i need outbound nat?

thanks

If you only serve incoming requests the state will handle the returning traffic as well, so you don't need outbound nat. Try VIPs type proxyARP or CARP if you need layer2 traffic for these IPs. If you ISP is routing these IPs to you anyway type other will work too.
