Let us focus on the vtnet setup (will look at the jail later).
You say that you have a vtnet interface and two wg interfaces.
How is this part of the table:

vtnet:
                         14.3    stable/14
send w/o offloading       789          772
send w/  offloading       485          523
recv w/o offloading      1938         2052
recv w/  offloading       719          972

generated?
* Is the traffic directly going over vtnet?
* Or is the traffic going over wg, which then gets over vtnet?
* Does the traffic go through NAT?
*
