Rooting User Mode Linux Change Ip

[dd163]

hi
I prepare to check test network. in that way i use UML (User Mode Linux). and my real OS is Redhat 9 and Virtual OS is Redhat 7.2

when i set ULM in my Linux mashin it routing well.

it can ping real OS and external IPs.

but when i change the UML ip address it wouldn't route.

it can ping real OS but cannot ping external IPs.

I change /etc/sysconfig/network-scripts/ifcfg-eth0 like that:

IPADDR=172.22.1.101
GATEWAY=172.22.1.1
NETMASK=255.255.255.0
NETWORK=172.22.1.0
BROADCAST=172.22.1.255

old one is

IPADDR=192.168.0.144
GATEWAY=192.168.0.254
NETMASK=255.255.255.0
NETWORK=192.168.0.0
BROADCAST=192.168.0.255

when i change ip and restart UML. the routing table have still 192.168.0.254 and my new gateway too come. put it cannot route. when i see linux routing table. it was:

172.22.1.101 0.0.0.0 255.255.255.255 UH tap0
172.22.0.0    0.0.0.0 255.255.0.0     U  eth0
lo

i cannot change my routing tables both of real and ULM.
i confused there.

please help me.
thanks all

sincerely
dd
