yeah... shame on me, it was all my fault :( :lol: I tried dodging the bullet and not move to PCC instead of using ECMP+.... And this was the only fault.... corrected the routes and it worked like instant.... Will move to PCC at the weekend. In addition I will set my routers before the mikrotik in ip...

Have you checked if the public ip is correct? Of course, like I said, on android it´s working fine. In the wireguard log on windows it resolves to the correct wan public ip, so yes, 100% sure. My IP adress should one with location in germany (I´m german) - and my previous posted IP adress is a cell...

1. Remove persistent keep alive settings on the Mikrotik Router settings for client peers. These are useless. Tried, but had no positive effect, still same issue, but thanks for the advice, will remove it out of each peer. 2. Allowed IPs on windows, a. are you sure there are spaces between each ent...

Hmm, is there an MTU setting on the windows client??

If not try changing MTU on wireguard to 1500 from 1420 and if no joy go in the opposite direction 1400, 1380 etc.....

Yup key mismatch is a good place to start. Also any windows firewalls in the way? If android works fine, that rules out the MT as the issue!! I exported the working android config and imported it to 2 different windows installations, same issue, still no sucessful handshake. Windows firewalls are o...

I checked the public key on both configs (Mikrotik + Client) multiple times, copy&pasted it, wrote the lines manual, no connection what so ever.... I´m 100% sure the config is correct, and like I said - I exported the working config from my Android device and imported it to windows, still - no h...

Hey everyone, I´m new to Mikrotik Routers and RouterOS7, but everything so went good so far. With my old router, which didn´t support Wireguard natively, I used a ubuntu VM for wireguard. There everything worked 100%, but my goal was to set up Wireguard on the new Mikrotik RB5009. So I set it up and...
