UDP ports

I'm a linux newbie. I'm using Suse 9.3.
How do I allow connections on udp ports? I tried through yast but I can't set a whole interval of ports. How do I do that?

Thank you very much.

Check out iptables. Here are some rules:

Code:

# allow udp traffic on port 100

iptables -A INPUT -s 0/0 -p udp --dport 100 -j ACCEPT

# allow udp traffic on port 1-10000 from 192.168.0.3

iptables -A INPUT -s 192.168.0.3 -p udp --dport 1:10000 -j ACCEPT

# allow udp traffic on all ports for everyone

iptables -A INPUT -s 0/0 -p udp --dport 1:65535 -j ACCEPT

man iptables should give you more info. rtfm. ;)
