How can i just poke a hole for a port, so it can use any traffic.
For instance I want to do this:
iptables -I INPUT --sport 123 -j ACCEPT
yeah why won't that work, i want all traffic to come and go on port 123

So if you find someone
Someone to have, someone to hold
Don't trade it for silver
Don't trade it for gold
I should think you'll want to use --dport (--destination-port) for that rule (since it's input... incoming destination). You also may need to have a rule for the OUTPUT chain, using --sport
iptables -I INPUT --destination-port 123 -j ACCEPT
iptables -I OUTPUT --source-port 123 -j ACCEPT
I haven't a clue about your firewall though and how the rulechains are set up but if those commands are issued after all the others, they should override for that port.
ah, i have to spell it out, i get yeah. I have my firewall blocking everything from coming in, so i'm not too worried about things getting out.
