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.
