Hi guys.
I'm experiencing a pretty weird wireguard, or perhaps
kernel/OS stack bits behavior.
I have three nodes which all can ping each other on wg0's
IPs but when I add a secondary IP:
-> $ ip addr add 10.0.0.226/24 dev wg0
it gets weird, namely, say when that sec IP is on
A -> B ping returns; C ping waits, no errors, no return
B -> both C & A pings return
C -> neither A nor B ping returns
I'm on CentOS with 4.18.0-301.1.el8.x86_64.
All three nodes are virtually identical kvm VMs.
any suggestions as to what is not working here or how to
troubleshoot are vey appreciated.
many thanks, L.
