Hi all, we are currently migrating to a new ISP, and we're wondering if can we use our old IP block as the internal NAT address with ATT's new IP block. We're planning on using MIP on a netscreen 25 f/w. It will be like this
server/clients (208.36.7.x) > ATT ip (12.54.120.x)>internet, that way the internal network is not changed, the DHCP servers will continue to provide addresses to clients, there's also DNS, email and web servers in the old IP block. Can anyone shed any light on this, what would be our best scenario, thanks in advanced.
