Weird connection problem - Netfilter?

[Andrew Greenburg]

Hi,

I've been using an iptables-based firewall at the office for several 
months, and all of a sudden today I started having problems with opening 
network connections to UNIX hosts. The port opens, and then it sits there 
for about 60 seconds before it actually responds. After that, the 
connection works normally. My tcp/ip connections to NT-based servers work 
fine. There have been absolutely no changes to the configuration of the 
netfilter box.

Any ideas?
