[Xen-users] vif-route/networking-route question

[Timo Benk <timo.benk@xxxxxx>]

Hi,

i set up dom0 to use vif-route and network-route instead of bridging
with eth0 = 172.48.0.128/12.

I created two domU's, xen-dom1 with vif = [ 'ip=172.48.0.101' ] and
xen-dom2 with vif = [ 'ip=172.48.0.101' ].

As expected, vif-route sets two static routes for vif7.0 and vif2.0:

---<snip>---
172.48.0.101 dev vif7.0  scope link  src 172.48.0.128
172.48.0.102 dev vif2.0  scope link  src 172.48.0.128
172.48.0.0/12 dev eth0  proto kernel  scope link  src 172.48.0.128
default via 172.48.0.1 dev eth0
---<snip>---

>From within dom0 i can:
- ping 172.48.0.101
- ping 172.48.0.102
- ping 172.48.0.1 (which is an external machine)

>From within 172.48.0.1 i can:
- ping 172.48.0.128
- ping 172.48.0.101  does not work
- ping 172.48.0.102  does not work

>From within xen-dom1 i can:
- ping 172.48.0.101
- ping 172.48.0.102
- ping 172.48.0.128
- ping 172.48.0.1   does not work

>From within xen-dom2 i can:
- ping 172.48.0.101
- ping 172.48.0.102
- ping 172.48.0.128
- ping 172.48.0.1   does not work

vif-route does not set /proc/sys/net/ipv4/ip_forward to 1 as 
expected ([1]), so i does that by myself.

Any ideas why i cannot reach 172.48.0.1 from within domU?

Greetings,
