i need to know if the following problem can be solved with an ISR x800 (adv sec image) and if it can, how.
The problem is: i have a single public ip and a server inside with a private ip.
I need to forward tcp (port 85) trafic coming from some public addresses to the internal server on port 86; and the rest of the internet coming on the same port (85) to the same internal server, but on other port (88).
I was thinking about someting like:
access-list extended ACL_1
permit ip the_public_ip_1 my_public_ip
permit ip the_public_ip_2 my_public_ip
match ip address ACL_1
access-list extended ACL_2
deny ip the_public_ip_1 my_public_ip
deny ip the_public_ip_2 my_public_ip
permit ip any any
match ip address ACL_2
ip nat inside source static tcp 192.168.0.10 86 18.104.22.168 85 route-map RMAP_1 reversible
ip nat inside source static tcp 192.168.0.10 88 22.214.171.124 85 route-map RMAP_2 reversible
But it does not work.
The reason for needing this is because i need to migrate from a linux to cisco and on the linux box it can be done.
