I have an old router that doesnt support being a VPN server.
I have a Mango, which I would like to be an OpenVPN server, BUT i need to be able to access other devices on my main internet router that the Mango is plugged in to.
Whenever I try to setup a VPN server on the Mango, I am not able to access other devices outside of the Mango or the main host routers web panel for example.
Would I neeed to plug the Mango in via the LAN or WAN port?
I’m guessing I would need to play with the advanced backend firewalling too?
Think of my problem as one where im trying to extend an old ASUS router with the Mango.
That sounds like the following, just with using a different GL.iNet router model and OpenVPN instead of WireGuard, but the procedure should be the same:
For OpenVPN UDP, port forward UDP Port 1194. If it still does not work for you, please provide more details on the connections and IP addresses/subnets.
I do not work for and I do not have formal association with GL.iNet
Assuming Mango WAN port is connected to the main router LAN port, the main router LAN IP 192.168.1.1 and Mango LAN IP 192.168.8.1 should be on different IP subnets. This is actually the correct setup and you should not change the Mango to be the same as the main router, or routing will not work. The Mango WAN IP should be on 192.168.1.x subnet of the main router.
When you start up the Mango OpenVPN server, turn on Allow Remote Access LAN
With this setup and with OpenVPN connected, you should then be able to open the Mango admin portal at 192.168.8.1 and the main router admin portal at 192.168.1.1. If not, then please post the System Log from the Mango router. I ran a quick test of the setup on my routers and it was successful.
