Hello,
I am trying to use port forwarding on a Cisco PIX 5520.  I use the Cisco ASDM Launcher to configure settings in this PIX BOX.  I am setting up an FTP Server on the same network, and would like to configure the PIX to forward a port to this server to enable FTP Access.  I am having some dificulty finding where to create these port forward settings.  Thanks for any help in this matter!

Are you trying to allow an internal FTP server to serve FTP requests from outside hosts?

I'm not sure from ASDM, but from command line try the following.

static (inside,outside) tcp <outisdeIP> <insideIP> 21
access-list <outside_int_ACL> extended permit any host <outsideIP> eq 21


You also need to enable the FTP application inspection to allow the data channel to be opened dynamically.

Chris,
After entering this command, I got errors.  One error was at,  ...... tcp <outsideIP>, and the other error was at,.....any host.  Any thoughts?  Thanks again!

Sorry I didn't have a chance to properly look at this again last night.

You nee to replace the <outsideIP> with your outside IP address. The same goes for the <insideIP>.

Also, try the below.

access-list <outside_int_ACL> extended permit tcp any host <outsideIP> eq 21

Unfortunately, the link PUNKY posted doesn't have the PIX/ASA devices on it.

BTW, Do you have a PIX or an ASA?

Also, which OS are you running?
