SuSE 9.3 Firewall Dropping Connections
 

I'm running SuSE 9.3 as a router between the following:

eth0 - External Network (Untrusted) - Internet Connection
eth1 - Internal Network 10.62.56.x (Untrusted) - Corporate Connection
eth2 - Internal Network 192.168.66.x (Trusted) - Local LAN

I've allowed access from eth2 to eth1 but NOT eth1 to eth2. If I transfer a large file or a large amount of files from eth2 to eth1 I'll get a message that the share is no longer available.

I'm not seeing any errors in /var/log/firewall

Any idea what would be the problem for the connection loss?

Thanks,
MePH

In what way are you allowing this access? Are you allowing established/related packets in both directions? What protocol do you use to transfer the files?

I've allowed all traffic to pass from eth2 to eth1. I'm just using Windows explorer to do a file copy to a network share on a Windows 2003 server.

What are the packet filters configured to do on the firewall? Is there anything significant about when it drops the connection?

Sorry I dropped the thread for a while .. Got busy ... Anyway I was watching log files today with this and there isn't any errors in /var/log/firewall or a tcpdump. They both just stop collecting data on the transfer.

my ip = 192.168.66.228
server ip = 10.62.56.3

Both these just stop dead if I start a file transfer which ends in the share is no longer available.
