[Xen-users] XEN 2.0.7 Routing

[Max E Baro <MEB@xxxxxxxxxxxxxxxxx>]

Hello Xen Users,

 

I thought I had this licked, but apparently not.

 

I am using vif-route on my XEN 2.0.7 server with kernel 2.4.30

 

My dom0 and domU are both configured with dual network adapters, one client interface and one management interface.  I installed iproute2 and have configured source based routing to direct traffic through the correct interface.

 

I have an external Cisco router that's used to access all domains.

 

My problem is as follows:  I can connect to my domU via the management interface when connecting via vpn into the cisco router.  I cannot connect to domU from the management interface network from other servers on the local side of the cisco router.

 

From dom0 I can ping the vif interface for domU and the eth interface inside domU.  From domU I cannot ping dom0 at all.

 

My configuration is as follows:  (Right now I will concentrate on the management interface as that is where my testing has been)

 

 

dom0:

 

eth0    192.168.1.2

eth1    192.168.44.4 (management)

vif1.0    192.168.12.1

vif1.1    192.168.43.1 (management)

 

[root@gemini /]# ip r
192.168.1.0/24 dev eth0  proto kernel  scope link  src 192.168.1.2
192.168.44.0/24 dev eth1  proto kernel  scope link  src 192.168.44.4
192.168.12.0/24 dev vif1.0  proto kernel  scope link  src 192.168.12.1
192.168.43.0/24 dev vif1.1  proto kernel  scope link  src 192.168.43.1

I turn on /proc/sys/net/ipv4/ip_forward and /proc/sys/net/ipv4/conf/*/proxy_arp in rc.local

 

domU:

 

eth0    192.168.12.2

eth1    192.168.43.2 (management)

 

[root@FSIDemo /]# ip r
192.168.44.0/24 via 192.168.43.1 dev eth1
192.168.12.0/24 dev eth0  proto kernel  scope link  src 192.168.12.2
192.168.43.0/24 dev eth1  proto kernel  scope link  src 192.168.43.2

 

Cisco router management interface is 192.168.44.1

 

From Windows PC on 192.168.44.8 I can ping 192.168.44.4, 192.168.43.1.  I cannot ping 192.168.43.2; I get the following message:

 

Reply from 192.168.44.4; Destination host unreachable.

 

Any help would be greatly appreciated.
