GL-AR750S-Ext VPN Policies work but kill internet

aelserafy · 2020-12-15T07:41:37.283Z

Yes, I mentioned the exact scenario and builds I tried.
To go further in details, I’m using Wireguard with Mullvad and the kill switch is enabled.

If killswitch does not enable, does the same problem exist?
Can you provide a screenshot of your configuration? I’m going to simulate the test.

The problem still exists even with the kill switch disabled.
Which config page would you like a screenshot of?

robotluo · 2020-12-16T11:49:13.188Z

VPN policy config page.

Tried it also with disabled “Use VPN for all processes on the route” and it didn’t work.
The behavior is a bit weird. Per page load I get few KBs transmitted but not all. For example, if I trigger a speedtest.net: ping passes, 1st speed figure appears then halts for a while and finally fails. And this is pretty repeatable as long as the VPN policy is enabled.

I tried every combination of vpn policy as well and just assumed it was still broken because nothing would make it work.

Any updates on this??

Seems this is related to the vpn service. Which one exactly you are using?

aelserafy · 2020-12-22T14:31:51.044Z

Wireguard on mullvad

Any updates on this?

I can confirm that this issue is also present on Firmware 3.105 when using Mullvad with OpenVPN and Domain/IP “Do Not Use VPN” rule. The “openwrt-gl-ar750s-fix-policy” firmware still works correctly.

modumb · 2020-12-28T13:41:29.860Z

vpn policies seem to work with proton vpn and open vpn for me for now on 3.105.

however, mullvad does not seem to work in conjunction with vpn policies (wireguard) still.

alzhao · 2020-12-29T09:15:10.544Z

Mullvad need the router to set up correct mtu to work. MTU is modified in 3.105 if there is any difference.

We will do extensive testing on this.

aelserafy · 2020-12-29T12:09:46.556Z

My trails on 3.104 was using a self set MTU.
In 3.105 was using the preset MTU.
In both cases didn’t work for me. All using Mullvad & Wireguard

aelserafy · 2020-12-30T15:07:13.983Z

the “fix-policy” firmware was based on v3.104, right?
where can i get it?

This is an email from their support…
"We will try to find out the old policy fix firmware and put it online.

Really have no idea because each time it works in my side."

Nick_T · 2021-01-03T10:16:59.635Z

I have the same problem with 3.105, I’m using ExpressVPN - openVPN. The openwrt-gl-ar750s-fix-policy fixed the problem.

robotluo · 2021-01-04T09:00:12.415Z

@aelserafy Using the same configuration on my side did not have the problems you described, but you can try the firmware in the link, I made some adjustments

aelserafy · 2021-01-04T14:45:13.269Z

This firmware has properly functioning MAC based VPN policy filtering using Wireguard and Mullvad.

qtmspin · 2021-01-07T16:32:50.680Z

This firmware seems to be causing my ar750 to lose connection. I’m using strongvpn and wireguard. Turning on the VPN policy seems affect everyone the same regardless if they are on the rules apply/don’t list. I’m pretty disappointed in the level of quality of firmware that is being released. It’s making me realize I probably need to stick to more established manufacturers. I don’t think Cisco or Netgear release firmware that has these types of issues.
