Odd firewall problems

I have a Linux system that is my firewall.

I host a game server on a different Linux system. "Counter Strike Source"

On the firewall the network traffic on the Internet side is 2-3 times as
high as on the local network side. Because of this I can't host a game with
more than about 3 people.

IFACE rxpck/s txpck/s rxbyt/s txbyt/s rxcmp/s txcmp/s rxmcst/s
eth0 68.88 50.57 20328.10 15793.68 0.00 0.00 0.00
eth1 51.38 66.75 8337.95 6013.03 0.00 0.00 0.00

eth0 is the internet
eth1 is the local network
If I stop the game server, both go near zero.

Data sent from the game server is received on eth1 and sent to the internet
on eth0.
Data to the game server comes in on eth0 and is sent out on eth1.

Note the number of packets is about the same. The numbers above are a 1
minute average using "sar -n DEV 60 1000".

The firewall is iptables.

Please help, or recommend a different list!
