More and more users do not have their own independent public network IP, which is a very troublesome thing when publishing some applications or websites to the external network. Please note that I am talking about the independent public network
IP does not mean that it must be a static public IP. Dial-up Internet dynamic IP is not necessarily impossible. What we want is that the gateway exit must be a public network IP, if your gateway router WAN
If the port is an intranet IP, it will definitely not work. To illustrate, the reserved range of ipv4 intranet IP: Class A 10.0.0.0-10.255.255.255, Class B 172.16.0.0-
172.31.255.255, Class C 192.168.0.0-192.168.255.255.
When I first found out a few years ago that peanut shells have the function of inner mesh penetration, I thought this was great. Build a small forum by yourself, there is no need for network administrators to do it on the gateway device
Port mapping, you can open the self-built forum directly through the domain name. But later, Peanut Shell agreed to start charging for free. At the end of last year, Peanut Shell pushed back to save users.
After the authentication, users can get 1G of free traffic per month, and it cannot be used after the 1G traffic is exceeded. And the certification fee is 6 yuan.
Today, I finally found a more reliable free intranet penetration tool ----- Netcom. This is a permanent free intranet port mapping and intranet penetration software. easily accessible
Connect to the intranet, 100% penetrate the intranet, no need to set up a router, no public network ip, no fixed ip, no dynamic domain name, users can add multiple mappings for free, suitable for companies and communities
Broadband, rental houses, campus networks, Internet cafes, education networks, etc. are used in environments with complex network structures and strict restrictions. Software download address:

personally tested it, the performance is relatively stable, there is no traffic restriction like peanut shells, and there is no so-called certification fee.
