ipchains :) >2) Can someone share a recipe to allow incoming/outgoing ssh traffic. I First, you have to allow traffic into the firewall: # Any packets coming from your internal network is good ipchains -A input -i eth0 -j ACCEPT # next allow ssh port 22 through the ppp0 port ipchains -A input -d <external-ip-of-firewall> 22 -j ACCEPT That's it. You put both commands in your ppp-up script. I did this successfully. In the ppp-in script there is a macro name for the ip address of the ppp0 port, and you put that variable ($ipaddr ???) in place of the <external-ip-of-firewall> and you are in good shape. Then, in your ppp-down batch file, you put one command: # kill the PPP0 port from a firewall standpoint ipchains -A input -i ppp0 -j DENY This ensures when you re-connect to the internet, or dial up server, the firewall commands have been cleared and not duplicated. Otherwise if you dial up, lose connect, and repeat 20 times (lousy ISP <G>), you end up with a giant firewall table that doesn't do much. Just slows Linux down unnecessarily. Hope that helps. I'm slowly learning, and got this far :) I'm working on port forwarding next.
