A ping does not work. The destination does not show up in the arp table on the Dom0 side, in fact there are no entries in the 10.32.0.0/16 subnet.
On the DomU side this command shows no results.

I think that by default SSH connections may be blocked without a specific exception being added to the firewall. Should I contact my sys-admin and request an exception be added? If so, what information would I have to give him?

Where I put <omitted> that address is not in the 10.32.0.0/16 subnet.
