I would seriously consider running a DomU dedicated as your outside 
router/firewall. I do that, in my case I use a Netgear DM111P 
ADSL-Ethernet modem and an ethernet card in the server. I use 
pciback.hide to hide the ethernet card from Dom0 and assign it to the 
router DomU (which runs Shorewall). IMO this gives you an easy to 
configure and easy to secure setup - your 'router' is a simple "two 
ethernet card" job, and Dom0 is not directly connected to the outside 
world.
As you've found out, the networking in Dom0 is non-trivial, and it's 
a lot easier to separate out the external routing/firewall functions 
into their own DomU.
However, I don't know what is required to use your outside interface 
in a DomU - all I can see is that it's a PPP interface, so is that 
using an ADSL modem card ?
