So thats what happened.
To summerise for everyone else.
I have a dedicated server. I can't use bridged network becuase my ISP drops
my network whenever the switch sees an unknown MAC.
So route is the way to go.
Here's what i did:
modify /etc/xen/xend-config.sxp to make sure these are uncommented:
(network-script network-route)
(vif-script vif-route)
comment our the bridge ones.
make sure you have in /etc/xen/scripts/network-route:
echo 1 >/proc/sys/net/ipv4/ip_forward
echo 1 > /proc/sys/net/ipv4/conf/eth0/proxy_arp
Setup your dom0 network like normal. You should set the default gateway.
My domU config looks like this (the important parts anyway):
vif = [ 'ip=domU_IP_HERE' ]
ip = "domU_IP_HERE"
netmask="255.255.255.255"
gateway="dom0_gateway"
The gateway is the dom0 gateway.
setup domU's network so that it has the domU ip.
Then add default gateway:
ip route add default dev eth0
I put that line in /etc/sysconfig/network-scripts/ifcfg-eth0 for centos.
AND THATS IT!!! and it works.
Just ONE LAST question please.
If i install shorewall do i need to make any changes? like turn on routing
in shorewall.conf etc
Please let me know. Also will it effect my domU's if i install shorewall in
my dom0?
Thanks to everyone for helping!!
