I have a client with BM 3.5 Enterprise. They use it for caching,
logging
who goes to what websites, Cyber Patrol, access rules and the
firewall.

My question is that we are thinking of eliminating the firewall
services and
replacing it with a 3COM firewall.

If we use only the only use the caching services of BM, will we then
loose
the other functions we need (Cyberpatrol, access rules, and logging
who goes
where) or does the caching services handle all this?

Any help would be appreciated.
