I've got my firewall more or less set up, but one thing remains. I
have two machines behind the firewall with ICQ on them; I'm running a
2.2.14 kernel with masquerading and port forwarding. Using plain
masquerading, I can get basic functionality, such as sending messages.
However, to get the other features to work, I implement IPPORTFW,
forwarding packets on TCP ports 2000-2020 to the internal MASQed
address on my workstation via ipmasqadm portfw. However, this method
requires me to port forward the external interface to a specific
machine on my private network; how do I set the firewall up so that
all users can gain all functionality?
(BTW, I tried the port 4000 mapping idea presented in the IP
Masquerade HOWTO; it didn't work for me)
Any help would be greatly appreciated. TIA!
