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

There's your problem then. Pretty basic IP stuff, not related to Xen. If your DomU does not have an IP address in the same subnet as your DomUs then it won't be able to communicate with them (at least without a router somewhere to move the packets about). This may also be the problem with other machines - it might not be the firewall, it might just be that there's no route for packets. As to firewall config, there's no way I could know, they can be set up with a wide range of policies ranging from one extreme of "everything blocked in and out except for the specific traffic that's needed" through to "fairly open and only specific stuff blocked".

The fact that DomUs can connect to the Dom0 does suggest that there is a gateway somewhere on the network. So have you configured NAT anywhere ?

PS - can you fix your mailer - it's a pain having to manually fix stuff that your mailer has helpfully broken by changing "10.32.0.0/16" to "<http://10.32.0.0/16>10.32.0.0/16". Just using plain text would do.
