Route to nowhere?

Hi,

HP-UX 11iV2, but it's probably universal (tcp/ip)

I have a production and a test server. The test server gets the application updated nightly from the production server software. The application accesses a set of process servers on a separate subnet (192.163.22.30,31,32), but reachable via the default route. The process server IP addresses are hard coded into the application (no, I can't use the hostname).

I want the test server to NOT be able to access these IP addresses. I tried setting up a non-existent route, but HP-UX tests to make sure the destination is reachable, and won't set it up.

Any ideas?

Thanks

I'm not familiar with HP-UX, but can't you use some packet filtering software to achieve this?
