VPN access - Doesn't work !?

I swear I've done that dozens if not hundredths of times. I'm trying to access a QS processor over a VPN.
I can ping it, It's set to DHCP but its IP was configured as a static lease in the router.

The IP for my computer is in the 10.0.42.0/24 range. The IP for the remote processor is 10.0.69.99.

I can't get 8.0.0 to connect. Doesn't work using multicast address (I wasn't expecting it to), doesn't work using 10.0.69.99 and port 8023 as remote access address.

I can ping it. I can open a terminal on it. Can't detect it. Can't get a diagnostic result either.

Found the problem. The remote access port had been changed (probably by me, yes).
