LinuxQuestions.org - How do I open ports on CentOS?

I need to open ports 1 - 35000 On CentOS 5, UDP and TCP Inbound/Outbound.

I know the security issues, I just need a solution.

My current Rules:

Quote:

-A INPUT -p tcp -m tcp --dport 1:35000 -j ACCEPT
-A INPUT -p udp -m udp --dport 1:35000 -j ACCEPT

NOTE: This is for a VPN.
