Ipsec assume
WebIPsec (Internet Protocol security) is the encrypted version of IP. Data packets sent using IPsec are scrambled so that only the two connected devices are able to interpret them, keeping their payload contents secure from anyone who might intercept the packets. IPsec is often used to set up Virtual Private Networks, or VPNs. WebConfiguring IPsec tunnel¶ Suppose you want to build an IPsec tunnel between two hosts. Assume host_1’s external IP is 1.1.1.1, and host_2’s external IP is 2.2.2.2. Make sure host_1 and host_2 can ping each other via these external IPs. Set …
