Allowing telnet access from outside my PIX firewall to a specific host

[chlorophyl]

I have seen some postings on this and thought I did everything I needed... However. I am trying to allow an isolated segment on my network access through my PIX firewall to telnet to a specific host on a non-standard telnet port (3340).

host/subnet information:

External Addresses:
Subnet: 192.168.1.0 255.255.255.0
Firewall: 192.168.1.1
Server: 192.168.1.3 (10.1.5.60 internally)

Internal Addresses of Interest:
Firewall Subnet: 10.1.171.0
Local Router: 10.1.171.1
Firewall Address: 10.1.171.43
Server: 10.1.5.60 (telnet to port 3340)

PIX configuration:

PIX Version 6.2(2)

Hmm, are you trying from a pc directly on the outside interface, you have no routing on the outside....your default route points to an inside ip.

Looks like a routing issue to me, cause the acl and the nat config is fine. All except for 192.168.1.3 being part of the global scope, you should remove it from the global commands.
