 The purpose of the ssh gateways is to give access to protected networks and resources (for a finite period of time). 
 
-Users are only supposed to use ssh to connect to the gateways as well as them to further connect to other machines. Never the less, for ease of use, there are some protocols/ports that can directly be accessed from the ssh gateway. These ports include: 5900 VNC, 3389 RDP, ICMP/PING.
+Users are only supposed to use ssh to connect to the gateways as well as them to further connect to other machines. Never the less, for ease of use, there are some protocols/ports that can directly be accessed from the ssh gateway. These ports include: 5900 VNC, 3389 RDP, 4000 NX, ICMP/PING.
 Therefore direct portforwarding on those ports will work.
