SSL VPN SOPHOS XG 19.5 Build 197

Hey Guys,

I have followed the guides for creating an SSL-VPN that authenticates through Active Directory.

When I have my laptop internal to the network and initiate a VPN connect it works fine. Connection is established. The logs show this.

However once I disconnect the laptop from the network and connect a modem it doesn't establish a connection. (Firewalls are off for testing).

I can see the modem's IP ( but eventually I get a time out)

console> tcpdump "port 8443"

listening on any, link-type LINUX_SLL (Linux cooked v1), capture size 262144 bytes

Any idea's on what the problem might be? Thanks Could it be the modems ISP blocking?

I don't think the sslvpn.log is showing anything when I try to connect from an external source. Lots of stuff in there when I connect from inside the network (which is pointless but did it for testing).
