Asus Merlin Router / OpenVPN client / Port forwards how?

[cw-kid]

Hello

I am struggling to setup a port forward to my IP security camera, so I can view it in TinyCam Pro app on my phone when out the house etc.

I have a Torguard Open VPN client running on my router and everything is behind that VPN tunnel.

I don't know how to do NAT where the external port number is different to the actual internal port number ?

For example I wanted the external port to be 8098 and the camera's internal port for the rtsp stream is 554.

I am using a nat-start file and I tried adding this and rebooting the router, but I still cannot connect to the camera.

iptables -I FORWARD 8 -i tun11 -p tcp -d 192.168.1.14 --dport 8098 -j ACCEPT
iptables -t nat -I PREROUTING 8 -i tun11 -p tcp --dport 554 -j DNAT --to-destination 192.168.1.14

192.168.1.14 being the IP camera.

I also on the Torguard client area in Port Management added tcp:8098.

However on a port checker site like this one, it says port 8098 is closed for some reason.

I have used the nat-start file before for my Emby Media Server and that works fine, however the difference there, is that the external port number and the internal port number are the same.

Any tips?

Thanks

iptables -I FORWARD 8 -i tun11 -p tcp -d 192.168.1.14 --dport 8098 -j ACCEPT
iptables -t nat -I PREROUTING 8 -i tun11 -p tcp --dport 554 -j DNAT --to-destination 192.168.1.14

This is the answer and its now working.

iptables -I FORWARD 8 -i tun11 -p tcp -d 192.168.1.14 --dport 8098 -j ACCEPT
iptables -t nat -I PREROUTING 8 -i tun11 -p tcp --dport 8098 -j DNAT --to-destination 192.168.1.14:554
