Hi,
I have been using UTM9 as a VPN appliance for years now with no issues until a few months ago when my Android devices can't access the network anymore. They can connect just fine, but traffic is not flowing trough the tunnel. I can't even ping the VPN gateway. On Windows devices everything is working just fine using the Sophos VPN client.
The UTM9 is behind a firewall and the proper ports are opened.
If someone has an idea, because I can't seem to figure it out. I will put the OpenVPN log here if it helps.
Thanks,
