Tp-link Router Port mapping 8081-Port Nexus Service Extranet Unreachable workaround

Environment Description:

Router: Tp-link tl-r478g+
Intranet Server Information:
ip:192.168.1.221
System: CentOS 6.5
Service: Nexus
Port: 8081

Mapping method:

Problem Description:

Other server services through this mapping method through the external network IP can be accessed, but this does not, the map when trying to change a number of ports is useless.

Problem Analysis:

The initial analysis should be the network configuration problem of the mapped server!

Solution:

Check the network configuration:
Vi/etc/sysconfig/network


Two lines in the red box are missing in this file configuration!

Vi/etc/sysconfig/network-scripts/ifcfg-eth0

Find the gateway here and the actual is also different to.

After both corrections, restart the network configuration
Service Network restart

Then use the external network IP access, haha, the problem solved.

Attention

My environment Intranet gateway is 192.168.1.2, usually 192.168.1.1
