XG behind NAT Router

Dave Hawkey

Hi, I have an ISP Router connected to the ISP (192.168.10.1), connected to a XG 106 (192.168.15.1) connected to a switch and devices (192.168.15.x).  Everything is working fine. 

I have now enabled VPN on the XG, and so have to forward ports from the ISP router, to the XG, but I can't because the ISP Router will only allow me to forward ports to the same subnet (ie:  192.168.10.x).

So I changed the LAN IP of the ISP Router to 192.168.15.254, but as soon as I did that I have lost internet connectivity.  

If I change it back to 192.168.10.1, I won't be able to use SSL VPN.  What am I doing wrong on the ISP Router?  

To confirm current setup: ISP Router 192.168.10.1 --> XG106 192.168.15.1 --> Switch 192.168.15.10 --> Devices 192.168.15.x

    For your ISP router, there will be two interfaces. One is connected to ISP link and another is connected to XG firewall.

    Kindly check on XG firewall from Network > Interfaces, you will see WAN interface with IP of 192.168.10.x.

    configure port forwarding on ISP router to the IP you see in WAN interface of XG firewall.
