port forwarding on a pix 501

[Laylobrown]

Is this good so far? I would like to be able to route access from any outside host that uses port 2100 to a specific internal host.

pix(config)# sho access-list

YOu have this line
access-list outside_access_in line 1 permit tcp any host 70.43.148.82 eq 2100

now add it to the interface
access-group outside_access_in in interface outside

add add a static to connect the internal IP to the external IP

static (inside,outside) tcp 70.43.148.82 2100 [INTERNAL_IP] 2100 netmask 255.255.255.255

Okay how does this look

pix(config)#

We are hoping to have gps units out in the field to access the server using port 21000 (i got the wrong information earlier).

 

[Laylobrown]

here is the static list

pix(config)# sho static
static (inside,outside) GPS_SERVER GPS_SERVER netmask 255.255.255.255 0 0
pix(config)#

Someone take a look at this and tell why the pdm is giving me issues about forwarding port number 21000 to a specific internal ip address? gps_server.

The first ACL you posted was correct. You need to follow the format for the static that I posted earlier. You cannot map the IP to itself.

access-list outside_access_in line 1 permit tcp any host 70.43.148.82 eq 2100
access-group outside_access_in line in interface outside
static (inside,outside) tcp 70.43.148.82 2100 GPS_SERVER 2100 netmask 255.255.255.255
