What can my ISP see?

[Indigo35 4]

When I'm using OpenVPN via a UDP port, what can my ISP see? 

 

I've noticed that in my Viscosity client there is a box to tick to send all traffic over it, but it's off be default. I'm assuming some OpenVPN command on the server forces all traffic to go over it?

I'm just really curious what they can (and cannot) see.

Hello!

 

That's correct, the purpose of that option is "redirect-gateway def1" which is already accomplished in our service. It's totally equivalent to tick that box or not.

 

Kind regards
