Hello,
I need some help opening ports.
I have an Optus Home Zone (mobile cell tower) that requires ports open.

Port
123 UDP
500 UDP
4500 UDP

I have assigned the Home Zone a Static IP outside the DHCP range and set the above Ports on the NAT, Virtual servers to that IP address.

I have used nmap to scan the ports and it provides open/filtered status for all of them.

Here is the kicker for me, i use a DGN3500 netgear (which keeps dropping WiFi hence its replacement) and enter the ports and it works straight away.
Un plug and put the Tp-Link and nothing.

I use Eset Smart Security, could that be the problem?

Any help please, as in order to have a phone in the house i need this Home Zone to work.

many thanks in advance
