I have connected a Tandberg video conference equipment outside the
firewall and assigned a real IP say, 202.195.123.123 to it. I only
turn on the video conference equipment when we need to use it.

Now I have a test server which is protected by the Netscreen-25
firewall and need to do some testing using a real IP. I don't want to
rent an IP for such temporary purpose. As the IP for the video
conference equipment is seldom used, I intend to map this IP on the
Netscreen-25 firewall to the testing server.

I would like to know if doing this, when I turn on the Tandberg video
conference equipment, will it cause any problem? If someone tries to
connect to 202.195.123.123, will it connect to the Tandberg equipment
or the internal test server?

I know that I could just remove the mapping on the Netscreen when I
need to use the Tandberg equipment, but it will mean that I want to
save the trouble.

What protocols are on the test server?
