Has anyone here had experience with the Nokia CC 500 or CC 2500?

If so, could you tell me:

1. Where are they typically placed? Behind a firewall or In parralell with a firewall?

2. If they are placed in parelell with a firewall are there issues which we would need to be cognizant of in order to protect ourselves in that configuration?


At work I may shortly have to start using these devices, and I have absolutely no knowledge about them at all. A google search brought up lots of different links to the Nokia PDF files, but nothing else....

Thanks,
