I am working offsite and successfully setup the XG 135 at home before it was shipped onsite, for installation by a colleague. We had an attempt to put it online but had to abandon this due to VPN issues, so now we are considering how to debug the problem. I thought I'd post here in case there are any ideas.
We have two broadband connections, and I configured a WAN port for each. One is our primary broadband and the other is the backup. Initially we connected the secondary broadband connection (physical port 4) and I was able to connect to the VPN through it. We then proceeded to connect the primary broadband connection (physical port 2) and received an email notification that it was online. However, we were unable to connect to the VPN through this broadband connection, and furthermore it was no longer possible to connect to the VPN through the secondary connection.
Due to time pressures we had to give up and will likely have to schedule another attempt at a quiet time. In the meantime it may be possible to run some tests in isolation if we connect to the secondary broadband connection only.
The WAN uses a subnet of /29 (255.255.255.248) with a static IP whilst the secondary WAN also has a static IP on subnet /24 (255.255.255.0). We are using SSL VPN and the Sophos Connect client.
I would appreciate any suggestions about what may have caused the connection of another WAN port to stop VPN from working at all. We did try rebooting the UTM but that didn't make any difference.
