I have windows web server 2008, which doesn't have RIP, I also have VM installed on the same server (CentosOS),

Finally I made routing through the Windows server using the IPEnableRouter value from the registery, I set it to 1

the routing thru the windows went very smooth and everything was fine for (10 mins only), suddenly it stopped,

I tried to restart the server but no use, it looks like the network router chached a wrong value, or the windows server

after some wire sharking the network, I finally recognized that the windows server no longer response for the ARP question (Who has the IP 85.25.250.21?)

why?? I don't know

every time I reenable the routing by adding the ip 85.25.250.21 to the Windows server IPs then I remove it, the routing get working again for max 12 mins

please try to help me to fix the routing to be working forever

Thanks

Any errors in the event log? – Vick Vega Apr 29 '11 at 22:36
As I finally noticed, the windows server never answer the ARP message (who has the ip x.x.x.x) while it is in ipEnableRouter mode, thus the Juniper firewall expires the old ARP message after 10 mins, and re-Ask the same question again, so the windows server doesn't answer it, – Asim Garhy Apr 29 '11 at 23:49
