iptables and all traffic out

I try to do a commando who makes everything internal traffic from the servers behind iptables firewall can get out, but are unsure about how it should be done.

Any ideas?

ACCEPT net fw udp output

 

Didn't make much sense, do you want Iptables to allow all traffic in and out?

 

What are you running? BSD or Linux?

 

I have a server which is set iptables at once and it only gives permission to the IP address xx.xx.xx.xx can log in - no one else, but I want more of which can log on but can not just getting IPtables to understand the message.

Anyone have an idea on how to do?
