I too am having a similar problem. My ftp connection doesn't hang, but
I do get the error "Data connection refused" or something of the sort.
Basically, the syn packet is recieved one of my input rules ( ipchains -A
input -p TCP -i $externalinterface -s 0/0 -d 0/0 -y -l -j REJECT) which
bocks any connection requests (ie any SYN packets that are incoming) bocks
the packet and logs the attempt. The only work around I currently have is
to not include this rule in my firewall, but that isn't a very good option
because now I don't get the extra security that this rule offers.
Any help would be appreciated.
