addressed to a particular application (for example, Telnet, web, or SNMP) on
particular node within the cluster, it can specify:
• the IP address of the egress node as the destination address
• the port as defined for the application in question for the egress node as the
destination port
The egress node can then use the port forwarding table to translate the
destination port to the correct port and IP address for the intended target
node in the cluster.
For example, if Node 2 in a cluster has an IP address 182.168.5.2, then to send
Telnet (TCP port 23) traffic to Node 2, you must:
1 Define the following port forwarding entry on the egress node:
add port-fwd protocol tcp port XXXX dest-ip 192.168.5.2
dest-port 23
2 Execute the following command on your management station:
telnet Y.Y.Y.Y XXXX
where
Y.Y.Y.Y
is the public IP address of egress node.
The port forwarding table can contain up to 32 entries.
