I have an asa 5500 router. I am routing public traffic to one or more web servers that are behine the firewall.
I have a rule that NAT''s
outside xxx.xxx.xxx.001 on port 80, to private ip 192.168.1.101 on port 80
outside xxx.xxx.xxx.001 on port 1080, to private ip 192.168.1.40 on port 1080
outside xxx.xxx.xxx.001 on port 2080, to private ip 192.168.1.50 on port 2080
the first entry is an address in a NLB cluster that can be set to any server dynamically. Entries 2&3 alow me to direct traffic to a desired server (the 220.127.116.11 and 50 are not part of the cluster).
All this works fine. I want to duplicate this on multiple outside ip's. For example:
outside xxx.xxx.xxx.002 on port 1080 to private 192.168.1.40 on port 1080
When I try and configure this, I get an error saying it overlaps with another rule.
If this would work, I would use the host header to route the traffic in the web server to the appropriate site.
Is there a way to configure this? I am using the GUI to configure it.
