It was indeed obvious: if domU's IP is private, network-nat must be used.

I was also trying to figure out how to specify default gateway for domU
in routing configuration: I thought I should use IP of vif<domU>.0 from
dom0 for it, so I tried to find the determine the rule how it is chosen.
But it turned out it does not necessarily should be this IP, it can be
any IP from domU's subnet -- it looks strange, but works.

Same happens here. Can ping the Internet, but cannot get pinged from any
of the PCs in the LAN, nor ping them. I hope someone can throw some
light here with this routing thing, as I can't use bridging because the
server is also acting as a proxy-cache and router.
