This article describes how to configure RPC to use a specific dynamic port range and how to help secure the ports in that range by using an Internet Protocol security (IPsec) policy. By default, RPC uses ports in the ephemeral port range...
Ports are how computers keep track of different processes and connections; if data goes to a certain port, the computer's operating system knows which process it belongs to. IPsec usually uses port 500. How does IPsec impact MSS and MTU? MSS and MTU are two measurements of packet size. ...
To use protocols and ports as additional matching criteria, you need to enable the ESP service and UDP port 500. In NAT traversal scenarios, you also need to enable UDP port 4500. [DeviceA-policy-security] rule name policy3 [DeviceA-policy-security-rule-policy3] source-zone local [Device...
IPSec Protocols To provide security for the IP layer, IPSec defines two protocols: Authentication Header (AH) and Encapsulating Security Payload (ESP). These protocols provide security services for the SA. Each SA is identified by the Security Parameters Index (SPI), IP destination address, and s...
the Notify messages. The payloads use the generic ISAKMP payload header. The values of the payloads are the hash values (IKEv2 uses SHA-1) of SPIs, IP addresses, and numbers of the ports for sending data packets. The hash value is computed as follows: hash = SHA-1 (SPIs|IP|Port)....

AH and ESP are network layer protocols and do not involve ports. To ensure successful IPsec tunnel setup, you need to configure a security policy on the gateway to enable the AH (IP protocol number 51) and ESP (IP protocol number 50) services. IPsec VPN vs SSL VPN IPsec and SSL are ...
Network Ports and Protocols Used by IPSec Related Information In the Microsoft Windows Server 2003 operating system, Internet Protocol security (IPSec) helps provide defense-in-depth against network-based attacks from untrusted computers. IPSec provides protection from attack in host-to-host, virtual...
