We use IP tables for our Dom0 all the time.  The DomU's have their own
iptables, specific to them.  We only allow access to our Dom0's from the
administrative team.  This means the only way a Dom0 could be
compromised is by one of us, which is extremely unlikely.  The DomU's
have various access configured for their specific needs.  We've had zero
problems with this strategy and it continues to work well for us.
