LS300 forwarded port closed

Hi,

I am currently facing an issue with port forwarding.

I have a device connected to the airlink LS300 modem in ethernet (with 192.168.13.99 as assign IP address)
This device expose a web admin interface on port 443.

I want to perform a port forwarding in order to expose this web interface through the LS300.

There is the architecture :

  • The LS300 is registered on a VPN with 10.30.0.110 as IP address
  • I am connected to the VPN also
  • I can access to the ACEManager remotely, via the VPN network, on : 10.30.0.110:9191
  • The other device is connected to the LS300 with the local IP address 192.168.13.99

Until there, everything’s ok. I can ping the device from the modem.

I added a port forwarding rule to the LS300 via the ACEManager : I forward the port 443 from the IP address 192.168.13.99 toward the port 9192 of the LS300.

There is the problem, the port 9192 of the modem is still closed, and therefore, I cannot reach my device web interface.

Is anyone faced a similar issue ? Any idea ?

Thank’s in advance !
Regards
