The above L2TP one-button installation package is also based on Openswan + XL2PTD source code compiled, I was also reference GKP build VPN, at that time with the 64-bit CentOS 6.2, has been unsuccessful. Now the space moved, I simply put the Linode system reinstall the 32-bit CentOS 5.6来 do the experiment.

Due to historical reasons, one of the problems with deploying L2 Tunneling Protocol (L2TP/IPSec) with Internet Protocol Security is that the IPsec dialogs after Network Address Translation (NAT) cannot be located. Internet service providers and small office/Home Office (SOHO) networks usually use NAT to share a single public IP address. Although Nat helps to save the remaining IP address space, it also brin

In win2003, The netsh IPSec command is used directly, ipseccmd is used for XP systems, and ipsecpol is used for 2000. Common parameters are as follows:-W Reg indicates that the configuration is written to the Registry and remains valid after restart.-P specifies the policy name. If the policy name exists, add the rule to this policy. Otherwise, create one.-R: Specifies the rule name.-N indicates the operation, which can be block, pass, or inpass. It m

SummaryInternet Protocol Security (IPSec) filtering rules can be used to protect Windows 2000-based computers from web-based attacks caused by viruses, worms, and other threats.

Introduction to IPSec:
IPSec provides a series of protocol standards, the IPSec protocol is not a separate protocol, it gives a set of architecture applied to IP network data security, in the peer selection includes network authentication protocol authentication Header (AH), Encapsulating Secure Payload Protocol Encapsulating Security Payload (ESP), Key Manageme
As we all know, although the basic firewall in Windows is robust, it has a single function and is more powerless to actively send packets. ipsec is a good supplement, but the operations in the ipsec graph are very clumsy, most of the ipsec Security Configuration scripts circulating on the internet can only run once.

Abstract:The Transmission Control Protocol (TCP) designed for wired networks has many incompatibility issues when applied to wireless environments and must be modified. At present, we have proposed several improvement solutions for TCP protocol in the wireless network environment, but these improvement solutions conflict with the IP Security Protocol (IPSec.
