Sophos XG and Tailscale

l0rdraiden

Is anyone running tailscale behind Sophos XG successfully?

My connections go through the relay but connectivity is allowed I only have blocked connections to SophosXG IP (appliance access)

Documentation doesn't say a lot

    Depending on the scenario, you won't be able to connect directly to another tailscale client. The first denied connection on your picture is the client trying to use UPnP to open a port, since XG doesn't support It - It simply blocks the connection. (For a good reason.)

    Does your ISP use CG-NAT? Or do you have a valid (public) IPv4 address?

    If you suffer from double NAT, you will have way too many difficulties using tailscale or even zerotier since It mostly relies on UDP punch hole as a way to initiate a connection between two clients.

    I have a public IP (no CG-NAT), so even with this if Sophos doesn't support UPnP to open ports there is no way this can make a direct connection?
