In computing, Internet Protocol Security (IPsec) is a secure network protocol suite of IPv4 that authenticates and encrypts the packets of data sent over an IPv4 network. IPsec includes protocols for establishing mutual authentication between agents at the beginning of the session and negotiation of cryptographic keys to use during the session. IPsec can protect data flows between a pair of hosts (host-to-host), between a pair of security gateways (network-to-network), or between a security gateway and a host (network-to-host). Internet Protocol security (IPsec) uses cryptographic security services to protect communications over Internet Protocol (IP) networks. IPsec supports network-level peer authentication, data-origin authentication, data integrity, data confidentiality (encryption), and replay protection.

As organizations increasingly rely on virtual private networks (VPNs) to safeguard their data, the need for robust and flexible networking solutions becomes evident. One such solution is the integration of Dynamic Host Configuration Protocol (DHCP) over IPsec (Internet Protocol Security). While IPsec ensures secure data transmission by encrypting and authenticating IP packets, DHCP simplifies network management by dynamically assigning IP addresses to devices.

This article provides an extensive configuration example with details on how to create a tunnel connection between two IPsec instances, both of which are configured on RUTxxx routers,  while one of them is a DHCP server.

The IP provided by the DHCP server over IPsec will be defined as a second IP in the IPsec Interface and name as Virtual IP.
