I'm using SuSE 9.3 as a router between 2 networks (eth0 = 192.168.65.0/24 & eth1 172.16.72.0/24). I'm having a problem when transferring large files or a large amount of multiple files. I get an error message stating the network share is unavailable. If I transfer from 192.168.65.228 to 172.16.72.3 using Windows Explorer I get the network share is unavailable after a few moments. I've tailed (tail -f /var/log/firewall | grep 192.168.65.228) the firewall log and watched a tcpdump on eth0 and eth1. There aren't any error messages displayed or anything. The packets just stop. I have allowed access from eth0 to eth1 but not from eth1 to eth0. Could this be the problem? I need to open a port possibly for Windows network shares? Thanks for any help! Jason
