We have been assigned a new block of IPs xxx.xxx.69.0/28 in different range to our existing ips xxx.xxx.94.145/28. The new block is being routed directly to our existing outside interface xxx.xxx.94.146. I would like to add this new block to the outside interface then NAT the addresses to private internal networks like we do at present for xxx.xxx.94.146/28 to 192.168.101.0/24.
Is this possible on a PIX 515 Restricted Version 7.0(7)?
Do I need a new interface/sub interface?
Can I do it without a VLAN our switches don't support them?
Any help much appreciated
