Computer-A= can=20 connect to Computer-X, and then create a TCP session with services on=20 Computer-X directly over the wg0 interface. =2D Computer-B is behind the same NAT as Computer-A. It can also create a=20 connection with Computer-X. It gets a response pinging Computer-X on it=E2= =80=99s wg0=20 address, but it cannont create a TCP session with services on Computer-X ov= er=20 the wg0 interface. The only thing I have found that might be relevant is that A was the first = to=20 connect, so the NAT port assigned is the same as the port that wireguard on= X=20 is listening to. Where-as B gets assigned a random port on the NAT side. Th= at =20 may just be coincidental though. Downgrading to 20170613 and TCP sessions w= ork=20 from all connections again. =2DReuben
