Can you elaborate why you don't want to use bridging?
IMHO it's easier to setup, and you can still use dom0 as router. For
example, libvirt on RHEL create a NAT network for domU,
192.168.122.0/24, with 192.168.122.1 located on dom0's virbr.

So, my ISP giving my address 10.9.3.92/24. When I'm using bridging, for every DomU I must assign address from my ISP's network (10.9.3.0/24), for example 10.9.3.93. In that configuration everything works, I can ping IPS's LAN and Dom0 (10.9.3.92).

But, my IPS give me just ONE IP - 10.9.3.92. I can't use any other address. I'm afraid that my configuration will invoke an "IP address conflict". And, in either case, if I would like to connect to 10.9.3.93 from my Dom0? Where it will connect? to DomU or to real user of my ISP?

So, after 2 days of bridging magic, I decide to drop that idea and now looking for another solution.

Early, I have used Qemu and there was that configuration for net: tap0 is up and then some masquerading with iptables. Everything works. But, I can't adapt this solution to Xen (yet?).

That is ;-)
