    Hi everyone

    first of all I have to say I don’t know pratically nothing of Cisco firewalls but I’m in the need to temporarily configure an old Pix 501, port forwarding the tcp 32976 (I need to test Neorouter software).
    This Pix has already set a port forwarding for tcp 3389 to use remote desktop so I have to be careful not to stop this service.

    I paste a few lines to make understand how the pix is currently configured:

    access-list (fromout) permit icmp any any
    access-list (fromout) permit tcp any any eq 3389
    access-list (inout) permit icmp any any
    access-list (inout) permit ip 192.168.0.0 255.255.255.0 any
    access-list 102 permit ip 192.168.0.0 255.255.255.0 192.168.101.0 255.255.255.0

    static (inside,outside) tcp 10.77.2.76 3389 192.168.0.1 3389 netmask 255.255.255.255 0 0

    access-group (fromout) in interface outside
    access-group (inout) in interface inside

    to open port 32976 I’ve addedd the following lines:

    static (inside,outside) tcp 10.77.2.76 32976 192.168.0.1 32976 netmask 255.255.255.255 0 0
    access-list (fromout) permit tcp any any eq 32976

    I didn’t add an access-group line because the (fromout) group is already active and I did not give the command “write mem” because i believe that I can test the pix anyway and then, after restarting the Pix, this returns to the normal function before the changes.

    to test if the port is correctly opened i go here: http://www.neorouter.com/checkport.php? and I see that the port 32976 doesn’t pass the test but even the port 3389, that was passing the test before, doesn’t pass this test too.

    Could you tell me where I’m wrong and how to open correctly the 32976 port?

    Thanks to all

    Dario
