Problems with Windows client

Hi
I've taken a futher look at this today with the latest client 0.3.1. The
issue is establishing a wireguard connection over a PulseConnect SSLVPN.
The Tunsafe client which works (I'm using an identical configuration on
both it and the Wireguard client) exchanges handshakes and then
Keepalives and then starts transporting packets.
My source address is 10.209.29.xxx and my destination address is
158.xxx.xxx.xxx. The config is as below.
After Tunsafe starts I see the routing created as:
C:\Users\whiskerp>route print /4 | find "10.2.80.226"
10.2.0.34 255.255.255.254 10.2.80.1 10.2.80.226 125
10.2.1.34 255.255.255.254 10.2.80.1 10.2.80.226 125
10.2.80.0 255.255.255.0 On-link 10.2.80.226 281
10.2.80.226 255.255.255.255 On-link 10.2.80.226 281
10.2.80.255 255.255.255.255 On-link 10.2.80.226 281
10.12.0.0 255.255.254.0 10.2.80.1 10.2.80.226 125
224.0.0.0 240.0.0.0 On-link 10.2.80.226 281
255.255.255.255 255.255.255.255 On-link 10.2.80.226 281
Wireguard client starts and exchanges handshakes, sends a keepalive but
it does not seem to get to the other end. After 25 seconds, a Keepalive
is sent by the other end (and noted by Wireguard at 10:04:41 in the
log). No traffic is sent.
The routing table created by Wireguard is slightly different too:
C:\Users\whiskerp>route print /4 | find "10.2.80.226"
10.2.0.34 255.255.255.254 On-link 10.2.80.226 5
10.2.0.35 255.255.255.255 On-link 10.2.80.226 261
10.2.1.34 255.255.255.254 On-link 10.2.80.226 5
10.2.1.35 255.255.255.255 On-link 10.2.80.226 261
10.2.80.0 255.255.255.0 On-link 10.2.80.226 5
10.2.80.226 255.255.255.255 On-link 10.2.80.226 261
10.2.80.255 255.255.255.255 On-link 10.2.80.226 261
10.12.0.0 255.255.254.0 On-link 10.2.80.226 5
10.12.1.255 255.255.255.255 On-link 10.2.80.226 261
Configuration:
[Interface]
PrivateKey = xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx=
Address = 10.2.80.226/32
[Peer]
PublicKey = QfjlPwEQa03gx7OYkM3Al8MIrfTx7WY0TT235eg0V1w=
PresharedKey = yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy=
AllowedIPs = 10.2.80.0/24, 10.12.0.0/23, 10.2.0.34/31, 10.2.1.34/31
Endpoint = iris-fw1.xxxxxxxxxx.com:21820
PersistentKeepalive = 25
I can connect with Wireguard to another server across the direct
interface just not via the PulseConnect SSLVPN. Tunsafe works in both cases.
The log is below. I do not see any repeated Handshakes in a Wireguard
capture of all interfaces, just the first one and the one 25 seconds
later from the remote side.

This is very strange.
