Re: [Xen-users] Re: (vif-route) DomU IP troubles beyond Dom0

Dumbo.  There is no bug in multi-homed Dom0 as I was searching for.  I simply neglected to MASQ the Dom0s effectively.
Further to my advice for other Gentooists.  This Relates more specifically to those who wish to use Dom0s as DMZs, and route to local lan via eth0 and net via eth1 (pppoe).

the sys-apps/iproute package was emerged.
I changed the line in /etc/xen/scriptes/vif-route that refers to Dom0's IP address.  Now all the Dom0 vifX.0 /32 IPs have an IP address independent of eth0.


Dom0 net config
# /etc/conf.d/net
modules=( "iproute2" )
# Gigabit LAN
config_eth0=( "" )
config_eth1=( "adsl")

DomU net config
modules=(       "iproute2" )
config_eth0=(   " peer" )

routes_eth0=(   " dev eth0"
                " via"
                "default via dev eth0  mtu 1492"

Hello again,
 As it would have it, the routing is OK. The (a) problem was with my DSL router, not knowing the existence of the internally routed Xen network. A static link on the router did the trick.  As for the MacOS X 10.4.5 computers not responding to ping? who knows.

 The vifname= problem/bug persists though.
The interface works fine, there is just no sign of it in xentop.
I wonder if shorewall can specify interfaces my MAC address?

Nevertheless, for any other gentooists out there who may be interested, these are the Xen configs I used. USE & CFLAGS are on my previous post.
