Hi,
I need some help with a new configuration on an existing production setup.
Currently we have this configuration running in production
ISP 1 /240 Subnet | catalyst 2950 (all subnets go through this) | PIX eth0 | PIX eth1-4 4 Private 192.168.0.X/0 subnets
We recently got a second .240 subnet from our ISP and need hosts on the inside of the PIX have public routable IPs (because the application in not NAT aware). The issue is, the second subnet is on the same wire and is a separate subnet. The ISP is not able to move quick enough to drop me a new cable or change routing rules on their side, so I'm stuck with implementing this with what I have.
How do I put the second public subnet behind the PIX, if I plug in the host on the switch that needs the public IP it will be on the same broadcast domain as the public ISP and not route through the PIX and be protected.
ISP 2 /240 Subnets (on the same Cat5) | catalyst 2950 (all subnets go through this) | PIX eth0 | PIX eth1-4 4 Private 192.168.0.X/0 subnets PIX eth5(available interface on the PIX) (Public IPs) ISP Subnet
Thanks, Dan Foxley
