The examples in this article describe how Python implements IPSec-open permissions. Share to everyone for your reference. The implementation method is as follows: Windows comes with a command-line tool that netsh ipsec static add filter does not support bulk additions, and also adds duplicate rules in. I wrote Ipsecset in Python to solve the above problems, support batch additions, and avoid duplicate rule

IPsec VPN data transmission processThe following is a packet transmission process (such as ICMP packet) through the IPsecVPN tunnel. When the PC in the subnet is protected by the VPN on the left, if the data sent from the left PC is received by the Left VPN eth1 port and needs to pass through the tunnel, the data is sent to the left ipsec0 port for encryption (tunnel, ESP or AH ), after the password is added, the left eth0 outer port is sent to the et

Firewalls are often deployed on the edge of our network environment to isolate the network and protect the security of the Intranet and Internet. For example, in the edge network, MIP a public IP address to a VPN device on the Intranet, for the sake of security, EDGE networks need to have selective open ports or Protocols.

This document describes the dynamic DNS VPN in IPSec VPN, where two fortigate devices establish a communication channel between them, allowing the servers or hosts that the FortiGate protects to access each other. One of the fortigate uses static IP while the other fortigate uses static domain names and dynamic IP. Before you configure, you need to unify VPN policies and parameters such as schemas, encryption algorithms, authentication methods, DH gr

Theo de raadt, founder of OpenBSD, made publicA letter from Gregory Perry. Gregory Perry participated in OpenBSD encryption framework development 10 years ago. In his letter, he claimed that the FBI paid the developer,To add backdoors to the OpenBSD IPSec protocol stack..Now he makes the secret public because the confidentiality agreement he signed with the FBI has expired. The backdoor code that was added 10 years ago is beyond the control of the pub

Remoting was used in a recent project, which is said to be out of security considerations. However, the development efficiency is relatively low and complicated. Another security issue is that the machine on which remoting is located can directly access the database, while the app server can only perform operations on the database through remoting, in other words, only the remoting machine is allowed. Other machines cannot directly access the database. You need to configure it on the server.
