Re: port 2122

Simple

static (inside,outside) tcp interface 2122 10.9.2.202 2122 netmask 255.255.255.255

access-list outside_acl permit tcp any interface outside eq 2122

access-group outside_acl in interface outside

Re: port 2122

Danny, were you able to open up the necesary 2122 tcp port you had asked, just want to make sure you are ok with configuration or if you need more help, just let us know.

Re: port 2122

i understand

this line:

static (inside,outside) tcp interface 2122 10.9.2.202 2122 netmask 255.255.255.255

and this line:

access-list outside_acl permit tcp any interface outside eq 2122

I don't understand

this line:

access-group outside_acl in interface outside

my confusion is: as reading this last line that you are telling the "access-group outside_acl" to use "interface outside" for all the incoming connections... but the rdp port 3389 and the media port 5001 are working even now without this line?

elaborate please...

Re: port 2122

When you issue access-group outside_acl in interface outside after the access-list outside_acl permit tcp any interface outside eq 2122, you are applying the newly created line in access list outcide_acl to the outside interface, if you don't apply it the outside interface most likely will not allow tcp 2122 towards the natted address.

3389, 5001 are working because at some point in time the outside_acl access list for those ports were also apply to the outside interface in the same fasion.
