Can I ask a silly question
These IMAP packets are coming from the net ?
Do you have a router aiming the incoming packets towards the intended box ?
Does it work with the firewall turned off ?
Cheers

I'm trying to use SuSEfirewall 2 to pass incoming IMAP connections to the computer on my network that has an IMAP server running. However, I do not seem to be able to access it.
The settings in the masquerade rule are: Source network 0/0 protocol tcp Req IP <actual internet address> Req port (imaps) 993 Redir to IP 172.16.1.10 Redir to port (imaps) 993
As far as I can tell, those are the correct settings, but I cannot even telnet to port 993 at the desired address. Get connection refused.
Also, www.grc.com shows that port open, but nmap does not. Any ideas?
tnx jk
I have also tried without Req IP specified, resulting in the line: FW_FORWARD_MASQ="0/0,10.0.0.0,tcp,113 0/0,172.16.1.10,tcp,993" in SUSEFirewall2, as described in http://chorgan.provo.novell.com/susefirewall2/web/FAQ.html#id2480008, but it still doesn't work.
