My BM3.8 is currently set up with a Private & Public interface and is
performing HTTP Proxy, VPN & Firewall services. We are planning on changing
it so the BM server is only doing HTTP Proxy while new Cisco equipment does
the VPN & Firewall.

I think the best way to proceed would be to remove the Public interface from
the BM server because it will no longer be needed (if I'm mistaken please
let me know).

The main question I have is regarding my gateway address. Would you
recommend changing the BM server address which used to be the gateway
address from say to another address, and make the new router
address Or, keeping the BM address at and
assigning an unused address to the router, say

Thanks for any help you can provide,
