How do I permit passthru on a Cisco ASA 5505
Posted on 2010-09-18
Hi, I have a ciscoe asa 5505 firewall. I have it all configured so that everyone works great, except I can have a server communicate with itself using any outside IP. I am curious to know how I can do this. Any option that will work is excellent. The server is nothing that needs to be secured or firewalled really, the basics of any protection it would need can be handled via software firewall, if an issues arrises. Also I have more than one external ip, in fact I have one for machine on the inside, so giving that particular machine an static assigned external ip is not an issue. I basically just need to be able to set the external ip with a listening port so that people from outside can access it, but at the same time I need for that machine itself to be able to verify that the service is readable. So it needs to be able to communicate with itself on the outside IP address. Screwy program I know. Any help is greatly appreciated.
