Hi Tim,
I suspect it is because you have the protocol as ALL, There are more
protocols than TCP and UDP.
You would need to create a rule for TCP and one for UDP if you want to
open the port for both.
iptables -A INPUT -p tcp --dport 3977 -j ACCEPT
iptables -A INPUT -p udp --dport 3977 -j ACCEPT
Failing that you could use
--destination-port
instead of dport.

David

I am running Debian and I am trying to open 3 ports realising I am
using iptables I tried the following (as interpreted from a few pages
I googled):
iptables -A INPUT -p ALL --dport 3977 -j ACCEPT
but I get the following error
iptables v1.4.21: unknown option "--dport"
But dport is listed in many of the results I googled, has dport been
depreciated and replaced with something else??
This is for internal LAN operation not external internet access
Thanks in advance
Tim
Cheer David, it was the ALL that was causing the problem, changed it to
tcp\udp as you suggested and it worked, unfortunately it made no
difference to the issue I am having (getting a game to run over a LAN)
so I am off to look else where.
