Hi,

 

I have a WAN connection with several public IPs (28 subnet). I have configured the WAN2 like:

 

IP: 82.216.XXX.242

SM: 255.255.255.240
GW: 82.216.XXX.141

 

I then added all IPs (like 82.216.XXX.243, 82.216.XXX.244, 82.216.XXX.245, etc.) as WAN IP alias adresses.

 

Then, under "Transmission" "NAT" I added some port forwardings. I have port 10000 to be forwarded on the main IP (82.216.XXX.242). Hence, I left the "WAN IP" selection empty. 

When trying to add another port forwarding for the same port, but selecting another WAN IP (82.216.XXX.243) I get the error "The source port already exists for the chosen interface(s). Please change the source port.".

 

I even tried to set another WAN IP for my first port forwarding. Simply, so that a WAN IP is selected and that this field is not empty. Same result.

 

 

Is this a bug? Anything I did wrong?

It might not be supported on your model yet.

  @Clive_A I guess so and ordered a more "advances" model. ER7412-M2

But I have to admit that I was a little  bit surprised that a "business" router does not have that, for me, basic feature. Alias IPs does not make sense at all for that model.

I confirmed with the dev that the ER7206 V2 pre-release should support that.

As in your original post, there is no mentioning about the hardware version.
