Intermittent issues with accessing web page

Hi

I have recently installed OpenVPN on my "server" running Windows 10.
I'm using it to connect my iPhone to my home network.

I'm at the point where I can connect to the server, and I can reach all the devices on my internal network.

The one issue I'm having though, is that I have a web page running on the PC, where OpenVPN is installed, and sometimes I'm having some problems accessing this page using the internal IP.

My setup is:
Internal network: 10.0.1.0
OpenVPN network: 10.8.0.0.
Internal IP of VPN server: 10.0.1.3
Virtual IP of VPN server: 10.8.0.1
Web page running on: 10.0.1.3:####

Added to OpenVPN config:
topology subnet
push "route 10.0.1.0 255.255.255.0"
client-to-client
duplicate-cn

Other settings:
Static gateway added to TAP adapter: 10.8.0.2
Routing and Remote Access Service enabled
Internet Connection Sharing enabled on the internal network adapter (10.0.1.3)

I have set it up this way, because my router is an Apple AirPort Extreme, which absolutely does not support static routes. :roll:

The problem is:
Sometimes when I open a browser on my iPhone and try to access 10.0.1.3:####, the browser seems to be considering whether it want's to show me the page or not, and then it either shows the page after a while, or times out.
Sometimes it shows the page right away without any problems.

Is this simply just due to the fact that, when entering an IP address in the browsers address bar, the browser will first try to find the IP address somewhere on the local network (WiFi or 4G network) before looking on the VPN network, or is this just not the way things work?

Or could it be something with the way I have my VPN server set up?

I have no issues what so ever with accessing remote desktop (also on 10.0.1.3) using the MS RDP client, or accessing my KODI media player (on 10.0.1.30) using the KODI remote app.

I have looked in to the push "redirect-gateway def1" option, but I'm not at all sure, if this is the way to go.

I hope that some of you experts can enlighten my. 🙂

It is probably a bad setting in the web browser you use ..

You might be right.

I actually just realized, that the problem is also present when accessing the web page from a device on the internal network.
So perhaps it's not directly an OpenVPN problem, although the problem seems to have appeared after, I installed and set up OpenVPN.

I should clarify, that the internal web page I'm trying to access, is the web interface to my DVBLink TV server. It's running on port 8100 on 10.0.1.3.

I also have a "normal" web server (IIS) running on the same PC (port 80).
I have no problems accessing the web page on this server.

Does anyone have an idea why I'm having these problems?

If this topic is not within the scope of this forum, I guess this thread can be closed.

Try configuring that web server to use standard port 80 (temporarily) .. maybe that will work.

Thanks for the advice.
I will do some digging.

But regarding my OpenVPN setup, you don't spot any immediate issues?

I believe I may have solved the problem.

One of the the things I did, when setting up OpenVPN, was enabling Internet Connection Sharing on the internal network adapter.
On the Internet Connectiion Sharing tab, there is a check box called "Allow other network users to control or disable the shared Internet connection"

I remember that I disabled this setting, not thinking that it was important.
But now I have enabled it, and it seems to make a difference.

Since I enabled it, I have not had problems with accessing the DVBLink web interface.
