Title: NAT w/ Multiple External IP's
What is the best way to configure NAT on IPSO and IP330 so that I can have 1 real IP for the NAT pool, and several real IP's that map to different ports on the private network.
For example:
216.75.169.100 - Ethernet interface of router to internet
|
|
|
216.75.169.101 - External interface of IP330
|
192.168.1.1 - Internal Interface of IP330
|
|
|
|
|--------------|
| |
Machine1 Machine2
HTTP 80 POP3 110
SMTP 25
Machine 1 External IP is 216.75.169.102:80 and internal IP is 192.168.1.2:80
Machine 2 External IP is 216.75.169.102:110 and internal IP is 192.168.1.3:110
Machine 2 External IP is 216.75.169.103:25 and internal IP is 192.168.1.3:25
Catch my drift?
Can this type of Port Address Translation be accomplished with Firewall - 1?
If not, my cisco box can do it, but how will the firewall allow the traffic in?
