Hey there,

I am currently aboard and, for some reason, I cannot connect to the VPN at home.

I did test that the VPN works connecting via another VPN in Switzerland.

Is there any restriction / protection turned on that prevents connections from the East Europe? If yes, would it be possible to turn them off?

Thank you,

Daniele

hello daalbano

There’s no such restriction.

There might be other problems:

Your home IP address has changed?
The DDNS didn’t get updated?
Your Connect Box 3 changed the operation mode back to Router Mode?
Your home VPN server isn’t on or isn’t online?

Hard to tell, what it is that doesn’t allow you to connect to your home VPN.

daalbano We have no such geo-restrictions. However, if you have the VPN service on a NAS, it is possible that GEO blocking is active there?

Via double hopping through another Swiss VPN I have access to, I can connect without issues.

At this point I am suspecting it’s some sort of packet inspection, I brought up a simple HTTP server on a random port and it worked just fine, the VPN itself is not on a standard port so it’s not just the port being blocked.

Considering HTTP works I will tunnel the VPN over a HTTPS+Websocket and happy days.

Thanks for the help anyway!

Daniele_Sunrise I wrote a small software to tunnel the VPN connection over a websocket (udp -> websocket) and wrote a small server (websocket -> udp) that I installed at home remotely and everything works fine now.

It’s clearly some kind of filtering, at this point if there is no geoblocking from sunrise I think must be some L7 filtering from the provider I am connecting from 😐 For the VPN I am using wireguard which, sadly, it’s an highly identifiable protocol.

Anyway, the problem is sorted out for now so all good! Thanks for the suggestione!
