Getting 789 errors when trying to access outside VPN's

Thu Nov 17, 2022 4:55 pm

I have some servers on a Mikrotik network that are working fine and they need to connect via VPN to a network outside connecting to a Meraki router. I am using the builtin Windows VPN with L2TP and settings that work fine from other PC's around the network and every time I try accessing I get a 789 error. Tried on Windows 10 machines and Windows server 2019.

The remote network never even sees an attempt. I can access fine from my home PC running on T-mobile but using the same settings on devices on my Mikrotik network always get a 789.

Any thoughs on whats going on that i am missing? Seems to be Mikrotik related as same setting work fine elsewhere.

Have you tried making any changes that can be found through the search?

Found the problem. Had port 500 blocked in my forwarding rule. Disabled and now everything is working.

Thanks!
