 · They use IPsec to communicate with other devices in the isolated domain. Connection security rule: A rule in Windows Defender Firewall that contains a set of conditions and an action to be applied to network packets that match the conditions. The action can allow the packet, block the packet, or require the packet to be protected by IPsec.  · In the following chapters you will find a detailed description of how to setup firewall rules for IPsec VPN connections. The experienced reader may notice that nowhere iptables IPsec policy rules are used (-m policy –pol ipsec). The reason for that is a special VPN scenario where both tunnel ends use overlapping IP addresses.  · IPsec Site-to-Site VPN Example with Pre-Shared Keys¶ A site-to-site IPsec tunnel interconnects two networks as if they were directly connected by a router. Systems at Site A can reach servers or other systems at Site B, and vice versa. This traffic may also be regulated via firewall rules, as with any other network interface.

CESG Infosec Manual V sets out a standard for configuration and use of the IPSec protocols to allow them to be used to protect RESTRICTED material. The standard is not intended as a replacement for cryptographic solutions using Baseline Grade evaluated products but is appropriate for smaller requirements where flexibility is important, as with mobile computing and teleworking. The UK government’s National Technical Authority for Information Assurance (CESG), advises organisations on how to protect their information and information systems against today’s threats. Requirement:An IPsec client which is assured under the CESG CPAscheme against the IPsec VPN for Remote Working ­ Software Client security characteristic, configured in accordance with the PSN End­State IPsec profile: IKEv2, X,AES­ etc. PSN Interim IPsec profile (acceptable until ): IKEv1, X,AES­ etc.
