ANSWERED New DSL Router and now cant connect anymore

[2mD 1]

Hi,
we had a lightning strike recently, in which my DSL Router ( Fritz Box ) and some Equipment from my provider died.
After getting a new DSL Router ( Speedport Pro ) and having the technician from my provider over to replace their equipment down the street, i finally have internet again.

But now airvpn won't connect anymore, everytime it tries to check the route it times out. here is the Log:

You need to search for any possible filter against UDP or more generic filter. Assuming that the ISP is the same, the block could be self-inflicted. As you changed only the router, first check the various Speedport Pro filters. This router offers a very wide variety of filters, including filters on protocols and destination ports.

Kind regards

That's what i thought, but according to the manual, there is no way to disable the firewall on that DSL router.
The only thing I can do is forward ports. i tried doing that with port 443:



but it doesn't seem to work:

or am i using the wrong port ?

Update:
I couldn't get 443 to work no matter what I did, so I tried some others and selecting UDP 1637 in the Eddie settings/protocols does work now

 

[OpenSourcerer 1441]

Were you trying to forward port 443 on your router by chance? Don't do that, you only forward ports on AirVPN. Besides, port forwarding is for incoming connections. Don't open port 443 if you simply want to connect to AirVPN using port 443.

And also, I've got a spare Fritz!Box here if you're interested. Unless you're on VDSL2 Supervectoring I could send it your way. Drop me a personal message (in German) if you want.
