Why each option
In Check Point firewall environments, Manual Client Authentication via TELNET uses port 259, which is distinct from the standard TELNET port 23.
Port 23 is the standard well-known TELNET port for general remote terminal access, not the Check Point Manual Client Authentication TELNET port.
Port 264 is used by Check Point for the topology pull service (FW1_topo) between management and gateway components, not for client authentication.
Port 900 is the Check Point Manual Client Authentication port for HTTP-based authentication, not TELNET-based authentication.
Port 259 is the dedicated TCP port for Check Point Manual Client Authentication using TELNET. When Manual Client Authentication is enabled on a Check Point gateway, the TELNET-based authentication interface listens on port 259, allowing users to authenticate through a TELNET session to the firewall before gaining access to protected resources. This is a Check Point-specific port assignment separate from the well-known TELNET port.
