Ten minutes to configure Openswan, what to do, I don't want to talk about it here, I really don't know, just google it. For theoretical knowledge, please google. Here, we only want to configure the dead steps like 1, 2, 4, 5, 6, and 7 to ensure that the configuration can be completed. This is because there are a lot of materials on the Internet, but it seems a little difficult for new users, and it is not easy to configure it successfully. 1. system i

First, the software description1, Openswan IntroductionOpenswan is the best way to implement IPSec under Linux, and it is powerful to ensure the security and integrity of data transmission.The Openswan supports 2.0, 2.2, 2.4, and 2.6 cores that can run on different system platforms, including X86, x86_64, IA64, MIPS, and arm.Openswan is an open source project Fre

Recently, due to the high traffic of the primary data center, several independent hosts were purchased abroad for traffic distribution and cost. This requires two data centers.Data Synchronization, including MySQL, MongoDB, and reverse proxy. By creating a VPN using IPSec to connect two subnets togetherThe most suitable solution. We have initially considered using openvpn, but because our application involves a large amount of data transmission, the p

Conflict between IPsec and Nat For packets sent from the NAT server to the Intranet, you must modify the source address and source port to the address and port (or other Nat mode) of the server before forwarding the packets. This modification damages the integrity of IPSec data and causes the receiver to fail verification. In addition, the port information of packets encapsulated by ESP has been encrypted a

can be linked to the S1-S4. This restriction cannot be understood because, for a network-to-Network vpn, you do not need to explicitly specify the Intranet CIDR Block and gateway. Instead, you only need to specify the addresses at both ends of the negotiation, the previous ISA has made us feel too limited. I didn't expect the ipsec-tools to be even more powerful, not only a little confused.V. Level 5: openswan
