    Hi,

    create a Firewall policy rule to allow access to port 4500. You have to create a new protocol definition for port 4500 (TCP/UDP), or simply extend the Firewall policy rule which allows ICMP to the Server with the new protocol:

    Hi,

    you want to allow this port from the TMG Server (Local Host) to the external Server?

    Hi,

    Thank you for the post.

    You should create access rule to allow telnet from localhost to external and ensure the target 4500 port is open.
