iptables / syntax for opening ports

[e1guap0]

Gentlemen, what is the proper syntax for allowing certain ports to open on a redhat firewall / im using iptables.

ports 5678 and 5679

The reason I need this is to allow my windows CE device to attach to my linux box and sync with ximian evolution.

I have successfully done it and have synced all my contacts and appointments but i needed to shutdown my firewall to do this. By allowing only the above two ports I think this will work with the firewall on...

as always thanks in advances!

iptables -I INPUT 2 -s 0/0 -i xxx -p tcp --dport 5678 -j ACCEPT
iptables -I INPUT 2 -s 0/0 -i xxx -p tcp --dport 5679 -j ACCEPT

you will need to change the -i xxx the the incoming interface that you wish to open so if it was eth1 then youd put -i eth1 etc.

the -s 0/0 means any source address if you had a static ip and wanted to open the ports for that ip on then you could use 192.168.0.1/32 of course youd need to change the ip address for the one you use

hope this helps
