Have assigned telnet access to a static public ip to one of the LAN IP (HP-UX OS) and able to ping the LAN (HP-UX) from other public IP but not able to access the telnet and the same is perfectly working if assigned to some other LAN IP.(telnet perfectly working for the HP-UX machine in the Local LAN).
You permit telnet to that static NAT address in the access-list? Are the access-list counters increasing when you are testing? Have you verified in the PIX log file that a connection is occuring?
In that case it can be a server issue, some systems use hosts.allow to permit telnet connections, some have local firewalls, and some do reverse-lookup before permitting a connection. Check the server log files as well.
