Hi,

My bridging stops when I start a third Xen domain !?!?

I have a few domains  setup (mail, wiki, pbx).  If I start two domains
bridge networking works great.  But if I start a third, either the new
domains does not work or one of the other DomUs stops working!  By
stop working I mean I can't route traffic outside of Dom0.  I have
been looking at this on and off for a couple of weeks.  Any insight or
things I should look at would be greatly appreciated.

I don't want to bombard this email with 10,000 dumps.  I will gladly
post any information needed to figure this one out.

Basic network is a 10.20.10.X network.
Gateway is 10.20.10.1

Xen Dom0 IP is 10.20.10.125
Xen Mail domain is 10.20.10.150
Xen PBX domain is 10.20.10.152
Xen wiki domain is 10.20.10.153
