OpenVPN Server

Hello everyone, long time no see. I recently bought an ASUS DSL-AC55U router as I was switching form ADSL to VDSL and my router didn't support VDSL. According to ASUS, this router can host a VPN server, which can be a PPTP VPN or an OpenVPN VPN. As I'm an iPhone user, and iOS does not support PPTP, I went with an OpenVPN server. I enabled it, used settings I got from tutorials, used the default settings and the results are all the same: I can connect to the VPN, but webpages won't load. These  are my current settings. Can anyone figure out why the webpages won't load? I've been googling it for days now.

 

Many thanks, Bruno.

What private IP Address is your phone given when you use the VPN and what's the private IP Address of the router? What is the default gateway that your phone should have and what does it have? Do they match? If so, can you reach the default gateway via something like ping?

 

Also as a simple check, are you using http or https? If http, should you be using https?

As per above I'm also curious, do your VPN subnet and lan subnet have the same address space?

I can't check that as webpages won't load, however, in the VPN settings, the VPN server shows up as my home IP. As for the default gateway, as I'm using LTE, I can't check that. As for reaching the default gateway, I'm not quite sure what you mean :S.

My VPN subnet is 10.8.0.0 and my LAN subnet is 192.168.1.1. If this was a stupid answer, please forgive me, networking isn't my strongest subject.

Hmm can you try moving your VPN subnet into the 192.168/16 space like 192.168.2.0/24 or similar?  Can you access internal resources like the 192.168.1.1 page over the VPN?  I'm curious if the Nat policy on the router is limited to a certain range.

I can indeed access the router's settings. As for the VPN subnet, what exactely do you mean by "192.168.2.0/24 or similar"? I changed it to 192.168.2.0, I'll export the file to my phone and test it now.

The changes above didn't change anything. The webpages still won't load
