Wan is 202.99.160.1, the subnet mask is 255.255.255.0, the IP address that can be used for the conversion is 202.99.160.2. Requires that the internal URL 10.100.100.1~10.100.100.254 be converted to a legitimate IP address of 202.99.160.2. The first step is to set the external port.

NICs, one Nic, and one Modem card must be installed on the computer running the Linux firewall. This article takes two NICs as an example. Install the NIC, correctly set the interrupt number and port number, and assign an appropriate IP address to each Nic. 　　 Configure the firewall model. 　　 2. install the Gateway 　　 There are two ways to install the Gateway: one is to run linuxconf, enter the ROUTINGANDGATEWAYS option, configure the gateway, and the other is to modify the rc. inet1 file.

In Linux, IP addresses were dynamically allocated using automatic IP addresses. Although the ip addresses obtained each time are the same, I decided to set an IP address by myself.

Winpcap like the C language. Besides winpcapy. py, the source code also provides several samples like Winpcap. Comparing the two sets of samples, we can find that the winpcapy sample basically translates the sample written in C language into the Python language, and the corresponding relationship is obvious. However, there is no filter code in the sample, so I will write a Python version of pcap_filter just like pcap_filter.c In the Winpcap sample. The main code about filter in pcap_filter.c is

author's server has two Ethernet cards, which are set in eth0 and eth1 respectively during core activation. These two cards are SN2000 ISA adapter cards without jumping feet, and most Linux systems recognize these two cards. The initialization steps of the author's Ethernet network are set in rc. inet1.
