From SSL VPN Client at Head Office to a Remote Sophos unable to connect to Web Interface either on 4444 or 443.
I am able to SSH to the device with no issues.
All of the firewall rules are in place at both ends, have multiple sites that work with no issue, just this one.
Yeah. IPsec is a different story. Die IPsec MTU is to big for the webadmin. Therefore this issue appears. Try this workaround: https://community.sophos.com/sophos-xg-firewall/f/discussions/104507/site-tosite…
Can you check the MTU Size on the TAP Adapter on your device (windows?)
Not sure it is that, I am able to connect to three other Remote Sophos Firewalls with no issues.
