Can someone clarify me on an issue I'm about to face:
My PIX515E is about to handle multiple different public IP ranges that are routed on a single cable from an ISP router, for example:
ISP router inside IP 184.108.40.206 / 255.255.255.248
PIX outside IP 220.127.116.11 / 255.255.255.248
PIX inside IP 18.104.22.168 / 255.255.255.192
PIX intf2 IP 22.214.171.124 / 255.255.255.192
PIX intf3 IP 126.96.36.199 / 255.255.255.128
The default route would be 188.8.131.52, without network-specific static routes.
The ISP router would be configured to route both 184.108.40.206 /24 and 220.127.116.11 /24 networks using a single cable towards the PIX outside interface. Will this pose any problems when one of the inside interfaces (intf3) belongs to a completely different network than the PIX outside IP?
How about when a host 18.104.22.168 tries try to access 22.214.171.124. Would the traffic be routed to the ISP router (126.96.36.199) which would turn it back towards the PIX or would it be routed directly to the right interface if the access-lists allow it?
