Hey everyone,


after bashing my head against what seems like a brick wall for days, I've decided here to seek help from some people more experienced than me. Long story short, I've had previous successful experience with port forwarding on two separate routers, but moved to a new flat with a new router and it doesn't want to play ball.

The router model is an Asus RT-n56U. I am trying to port forward a few specific ports (2934-2935, 9987-9989). My computer is assigned a static IP address (see here: ). 


Port forwarding is set up correctly within the router as far as I am aware (see here: ). 

Firewall rules allowing the ports are set. Additionally, I've attempted to turn of the local computers firewall as well, but the ports were still not being forwarded.


Additionally, the router firewall was disabled during these tests to prevent it from blocking any ports.




Seeing that this was not going anywhere, I attempted to set up DMZ to my local IP ( (see here: However, this again did not result in the ports being forwarded. 


I'm at a complete loss as to why this is happening. I've used the Simple Port Tester application to see if the ports are being forwarded correctly (




In case it is relevant, the router is connected to a Chorus Optical Network terminal (this is a gigabit fiber box in Dunedin). ISP is myrepublic. 

Any help would be appreciated, thank you in advance :)




Also, the machine in question is connected via Ethernet cable to the router.

MyRepublic use CGNAT by default and what really pisses me off is they're not at all transperent about it either (check out their Static IP page which doesn't really explain it either as they mention dynamic IP addresses by default). CGNAT means you're sharing a single IP address with many other customers so port forwarding is not possible. You're needing to request a static IP from them (again, they're not even transperent on the cost of this on their support pages but it does appear it is a once-off charge of $20 only found once I started a signup process) however it wasn't clear if this changes with specific plans.


Remind me to never try to find information on the MyRepublic website again - what a mess.
