iptables issue or no?

[Deleted member 27741]

Hi, I have a certain iptables rule that is driving me nuts.

When I add port forwards, everything is fine with all of them but one. It is a port forward like-
forwardname 6000 local.ip.address 6000

For whatever reason this and ONLY this port forward shows up in the NAT iptable with a dpt of X?
tcp dpt:X to:local.ip.address:6000

All others show a correct dpt. I have reset the router. I have deleted the rule and rebooted (and added rule again). Reset the rule multiple times (delete and re-add). Added the rule with a different name. Done a rain dance and used the force. Still can't get that freakin' rule in iptables to say the right dpt. The problem only occurs with the port forward to port 6000. Problem or no?

p.s. I call the nat iptable with this command:
iptables -t nat -L -v --line-numbers -x

I think it's showing X because port 6000 is the port used by X server.

Try adding the "-n" option to stop it resolving the names.

Its just resolving the port number.

admin@rt-ac68u:/tmp/etc# grep ^X /etc/services
X 6000/tcp

Great, thanks! What the %$@ is X server? I suppose I should move that service away from port 6000.

It's the windowing system used by most Unix systems. https://en.wikipedia.org/wiki/X_Window_System
