The test environment is as follows:

Outside the virtual cluster IP: 103.250.1.1 (web address) "=" 10.180.1.1 (103.250.1.1 NAT mapping network address)
Server node 2:10.180.1.20, 10.180.1.21

Now NLB deployment is as follows:
1, connect to an existing server 10.180.1.20
2, set the cluster IP10.180.1.1
3, select the multicast model
4, polymerization
5, increase 10.180.1.21 node in the cluster

Question:
Test network environment can (open the application on the server (port 1234), install client in 10.180.1.101 Telnet port 1234 is tong)
But outside network environment can not be (client to access the Internet 103.250.1.1, or telnet1234 port impassability!)

Excuse me what reason be

Network to network with NAT outside, outside the network to the network using port forwarding
