Bridge not working and can't ping gateway

Hi everyone,

I wonder if you can help. This has baffled me.

I have a Centos5 host and a centos5 guest in vmserver 1.0.10. I have another gust XP.

I have two NICS eth0 and eth1[used for internet/don't care about it]

Host has ip 192.168.123.141 and gw 192.168.123.254

Guest has 192.168.123.146 and gw 192.168.123.254, bridge

XP guest has 192.168.8.2 and gw 192.168.8.1, host only

I can ping from XP>>host>>XP and access the webserver[host]

I can't ping host>>guest centos>>host. I can't even ping the gw .123.254 from either. I get Destination Host Unreachable

I have checked routing and it's correct, /etc/sysconfig/network-scripts all correct, vmnet0 is mapped to eth0, ifconfig correct.

I need an apache webserver on host and another webserver on centos guest.

Any ideas?

Thanks
