IPtables for WHOIS lookups from Server

It's not my favourite thing, IPtables.

I'm trying to punch a hole through the firewall so that my Server can do WHOIS lookups.

Can anyone please help ?

There are better ways of doing this but the following method opens up the WHOIS port entirely:

iptables -A OUTPUT -p tcp --dport 43 -j ACCEPT

iptables -A INPUT -p tcp --sport 43 -j ACCEPT

iptables -A OUTPUT -p tcp --sport 43 -j ACCEPT

iptables -A INPUT -p tcp --dport 43 -j ACCEPT

That should do it.
