I found out there is a critical alert in the log.
VIP server cannot be contacted.
What should i do?
Correct the problem with the VIP server on

For some reason the netscreen can't talk to it.

I can ping the VIP server when telnet the firewall.
Any suggestions? Thanks.

Copy in the logs you see relating to this, so that we can see what you do.

I would suspect that the VIP is not responding on the port/service that is being forwarded to it.

Double check that.
I've found that the NetScreen will pop that error in the logs ALL THE TIME. I just turn off "Server Detection" in the VIP setup and the alarm goes away. As long as you can do what the VIP is configured to do, don't worry about what the Juniper says.

How can i turn of the Server Detection option form netscreen 50?
I can not find the options from the webUI. Or i only
can do it by CLI?
Please teach me some steps if for command line. thanks.
just append manual to your vip statement via cli to turn off auto server detection

for example

set interface ethernet3 vip untrust xxx "xxx" manual
manual               turn off server auto detection

you can also do this via the WebUI, just go to


select the Untrust Interface, then VIP,

then the desired vip services, and untick the box: Server Auto Detection
