Hi, I'm unable to setup a Wireguard VPN server on my Mango (GL-MT300N-V2) for using my home router IP address from a remote (client) connection.
I have a main router from my ISP to which I plugged the Mango router (WAN port on Mango to a LAN port on the main router).
The Mango IP address in the main home LAN is 192.168.1.55 (shown in the admin console, "Ethernet" tab, gateway and DNS server 192.168.1.1, DHCP).
I well configured the Wireguard VPN server; it is ON listening on the port 51820 (tunnel IP address 10.0.0.1/24); I created a client profile that I used on my client devices. The Peer section of the config file includes my public IP address and port 51820.
On my main router I configured a port forwarding for external port 51820 to 51820 on the Mango (192.168.1.55). I opened the port 51820 on the Mango too.
The port forwarding on my main router works well, as I tested by forwarding 51820 to internal port 22 on the Mango so I have an SSH access from Internet to the Mango. Then I put back the forwarding to 51820 (VPN server).
On my client devices, when I connect the VPN client I expect to have Internet access and the public IP address of my main router.
I don't understand what I'm doing wrong. My VPN tunnel doesn't work, there is no Internet access from my client devices.
Thanks for your advice. As far as I was able to check, it seems everything should be ok : network is separate (Mango range is 192.168.8.x and main router 192.168.1.x); I'm not behind a mobile network; port forwarding is ok; dynamic IP address: yes but in practice my public IP address hasn't change since weeks; the port 51820 is not blocked (I tested it); VPN conf seems ok.
Yes, I can ping the main router from internet, it works. And from Mango any internet host and my router public IP address. But I cannot ping from the main router, I dont have terminal access to it
When I use a VPN client within the internal LAN (of the Mango or the main router), it works.
But obviously I need it working when the client is on internet...
First thought is that the port forwarding doesn't work on the main router, but when I test (forward the port 51820 to other internal ports on Mango like 22 (ssh) or 80 (http)) I can reach the Mango from Internet.
