Port forwarding on ASA 5505 ver 8.4(7)

[harshil296]

Hi Folks,

I am trying to setup a port forwarding configuration of ASA in local network. Scenario is internet connected with DSL modem and ASA connected with DSL Modem. Modem redirecting all traffic to the single LAN IP (ASA).

Somehow I have tried to configured and its doesnot worked out so I configured agian basic connectivity with internet. I have two servers in inside network 1) 10.10.10.22 (S1) and 2) 10.10.10.100 (S2). I can abel to reach intenet from inside network but failed to configured port forwarding in ASA.

I would like to access servers from outside network using custom port forwarding. Need to forward ports 8080,443, 554, 8000 for 10.10.10.22 so whenever I request 192.168.1.100:8080 then its redirect to 10.10.10.22:80, 192.168.1.100:8443 to 10.10.10.22:443 or 554:8554 or 8000:8000, I also like to forward 192.168.1.100:80 to 10.10.10.100:80 & 192.168.1.100:443 to 10.10.10.100:443, however ASDM & SSH already enabled it is possible to foreard 443 port as 9443 for ASDM, if request 192.168.1.100:9443 then its point ASDM??

Can some one guide how to configure above requirement in current configuration on ASA 5505 8.4(7).

This is my 'show run':

First create a network object-

object network 10.10.10.22-8080

host 10.10.10.22

Then add a NAT

nat (inside,outside) static interface service tcp 8080 8080

You can only have one NAT per object so you'll have to create an object for each port translation

object network 10.10.10.22-554

host 10.10.10.22

nat (inside,outside) static interface service tcp 554 554

object network 10.10.10.22-443

host 10.10.10.22

nat (inside,outside) static interface service tcp 443 443

etc ...

Don't forget the ACL applied to the outside interface as well. Let us know if you need help with that.
