Rubik's Cube Cloud: Hong Kong HKBN NAT, dynamic IP automatic replacement, KVM virtual architecture, 20% off annual payment, 100M bandwidth

Mofang Cloud is a Chinese hosting merchant that has been established for 2 years. The merchant mainly sells VPS products, using KVM virtual architecture, and NAT chicken. The data centers are in Hong Kong, the United States, and Singapore, and all lines are direct connections. This is the CN2 line we are talking about. Yesterday I received a Children's Day event from a merchant (ok! It's not a holiday I celebrate). It is for a Hong Kong HKBN NAT VPS, sharing dynamic IP, 10 ports, 100Mbps bandwidth, and It comes with Ruisu + TCP bottom layer optimization, provides DDNS updates, and the IP will automatically switch. If you pay quarterly, you can get the initial installation fee for free. If you pay annually, you will get a 20% discount. However, the price is a bit high. I recommend it to friends in need.

NAT usage tutorial

• 1. Obtain DDNS domain name

Log in to the independent control panel (panel.gs), click on your NAT host control panel, and you can get the DDNS domain name in the format of xxxxxxxx.didiensi.com in the node name/Node Name, as shown in the figure below.

• 2.Port mapping rules

Each instance is allocated 10 ports, which is 0-9 of the port number, where 0=SSH port 192.168.C.D Corresponding port range C00D0-9 192.168.C.DD Corresponding port range C0DD0-9 192.168.C.DDD corresponds to the port range CDDD0-9

Example: 192.168.1.2 Corresponding port range 10020-10029 10020=SSH 192.168.2.25 Corresponding port range 20250-20259 10250=SSH 192.168.3.155 Corresponding port range 31550-31559 31550=SSH

• 3. Final application

Based on the dynamic domain name obtained in step 1 and the port obtained in step 2, the result in the following format can be obtained. xxxxxxxx.didiensi.com:xxxxx

Where xxxxxxxx.didiensi.com:xxxx0 is the SSH port, The remaining 1-9 are other application ports and can be freely allocated within the instance.

• 4. Expand usage

If the application you are running is inconvenient/cannot be changed to the specified port assigned by the system, you can use the following command to forward the port

TCP: iptables -t nat -A PREROUTING -p tcp –dport application listening port -j REDIRECT –to-ports NAT port

UDP: iptables -t nat -A PREROUTING -p udp –dport application listening port -j REDIRECT –to-ports NAT port
