I have two Ethernet cards in my machine - one for the cable modem and another for my private network and I use ipchains to masquerade through the cable modem. The problem is the connection is very slow on the private side of the network using samba or ftp back to the server and on the internet. I average 7k/sec transfers when it should be around 800k/sec +/- from the local server. Does anyone have any idea what this could be? The same machine worked fine with 5.3 Festen. I guess it is possible that this has nothing to do with forwarding at all. Here is the script I use to start ipchains... echo 1 > /proc/sys/net/ipv4/ip_forward /sbin/ipchains -P forward DENY /sbin/ipchains -A forward -s 192.168.1.0/24 -j MASQ Thanks! Beach
