[Solved] Issues w. Wireguard site-to-site after upgrade to 24.4 (Business)

[Hitman247m]

Hi Everyone,

I had a working Wireguard site-to-site connection, until I upgraded to 24.4 (site "A") today. The connection is successful, and devices from site "B" have full connectivity to the subnets in site "A", but not the other way around (A --> B). To further complicate the situation, the upgraded Opnsense box in Site "A" still has full connectivity to all the subnets in site "B".

I compared the routes on both Opnsense boxes, and nothing odd stands out.

I noticed a number of threads open for wireguard issues, but they seem different than my situation

For some reason, everything started working overnight, so issue resolved I guess
