I don't have the ability to test this, however;

If your router is capable of defining Static Address Translations (most Cisco 
ones are), create a static address translation from your outside address on 
port 5012 to your inside address on port 23. (Assuming you are using NAT on 
your router)

Then allow ISA server to pass this traffic.
Create a Server Publishing Rule for a Telnet Server.


Another way to do this might be to create the following in ISA Server:

1.Custom Protocol Definition
2.Custom Packet Filter for Inbound traffic
3.Custom Protocol Rule for Inbound traffic
4.Server Publishing Rule for this Telnet Server.


ISA server does provide a simple way setting up a static address translation.
However if you were using RRAS you could do this.

Let me know how you get on.

Does ISA server have the capability to translate ports?

For example, how would I publish port 5012 on ISA, and forward that to an
internal server on port 23?  If ISA can not do this (which I suspect), does
anyone know of another tool I might use.  Are there any shareware or cheaper
firewalls that might do this, that I can stick in front of the ISA server?
