The pix can be configured to only allow telnet from certain networks or devices.  It may also be configured to only allow SSH.  Without seeing the configuration it is impossible to tell.  If you cannot use https  telnet or ssh to reach it, then I would suggest connecting a serial cable to it and retreiving the config.

You can config your pix to allow you to telnet from any host like this:

> enable
> pass
# config t
# telnet 172.16.0.0 255.255.0.0 inside

but this not good for security, you can enbale it to accept only connections from your pc like this:

# telnet 172.16.10.5 255.255.255.255 inside

assuming 172.16.10.5 is your pc ip address

hope this helps!

You can also add multiple computers to be able to access your pic:

telnet 172.16.10.5 255.255.255.255 inside
telnet 172.16.10.7 255.255.255.255 inside
telnet 172.16.10.10 255.255.255.255 inside

Did you add your computer ip address to the config?

telnet 172.16.10.5 255.255.255.255 inside

where 172.16.10.5 is your computer ip address

or if you would like to access it from any host then use this:

telnet 172.16.0.0 255.255.0.0 inside

assuming your computer start with 172.16.x.x
if you have different subnet then it won't work.

hope this helps!
