[Bug]: Unusable network on Oracle Cloud (pure WG works fine).
Contact Details
No response
What happened?
I am trying to connect 2 different Oracle Cloud account via netmaker.
I am using netmaker.io free tier, software on both nodes is identical (Ubuntu 20.04), ports are open, and connection is estabilished.
For the sake of demo I am connected both via WG on port 51820 (subnet 192.168.220.0/24) and Netmaker on standard 51821
From one node to another starting with ping

Raising MTU of netmaker to the same value as wg (8920) helped with ping but not with iperf
