I connect to a range of servers hosted by one provider via a VPN. I can connect to the VPN fine, however when I then go and try and connect to the server(s) it fails.

A NAT'ed IP address that has worked up until today, has stopped working either via SSH/SFTP.

As you can see below, if I try and ping the IP then it responds with Destination host unreachable, but, for some reason it says the reply is from 192.168.0.8?

If it enter this IP address in my browser, I get nothing. Where is this IP coming from and is there any good reason why I cannot access the IP I am trying to ping?

I have the VPN remote host address of 80.75.67.x, which shows me as being connected. But i'm unsure if there is a config issue at the server side or my end that has caused this issue?

I have had some recent Win7 (automatic) updates, but it's hard to tell if that's caused this problem.

This is my output from arp:
