Ah, good info. I'll give that a try, thanks.
I'm just doing the prep work at the moment before I add any rules to the firewall.
All I've done is
Create the CA, for OpenVPN client
Create the OpenVPN client (showing as UP)
Create the interface OPT1 and set it to port ovpnc1
the problem i have is, as soon as i enable OPT1 interface and reboot, all my internet traffic stops
nothing has been configured by me to use OPT1, so why is this?
