1, to ensure the normal network applications
clearly LINUX network access address, and make sure LINUX server SSH service normally. As the network LINUX SSH access address is 192.168.1.29:22, the network can normally be accessed using SSH.
2, nat123 client for Linux installation start
#apt install mono-complete (centos, redhat refer to this post: https://www.cnblogs.com/jianzhou/p/12124150.html )

Mono nat123linux.sh Service &
Exit 0
4, visit the Web site remote web management
login site, the center left of the user, to add port mapping. Choose whole port mapping types. Fill LINUX fixed address within the network port, domain names and the Internet access. You can use your own domain name, you can use free domain names. Place the cursor input box there is the wizard prompts. Wherein the whole port forwarding mapping mode is P2P VIP line.
5, external network access to client-side installation and use nat123 visitors
nat123 window to download and install the software: http: //www.nat123.com/Pages_2_32.jsp
visitors open access to the port after the domain name and full LINUX port mapping. When added as destination address port, while allowing the check LAN access, local area network within the visitor can be accessed.
Visitors using this machine can be accessed LINUX. Access address is a local domain port open to visitors.
