What is IPsec VPN explain briefly?

IPsec VPN is one of two common VPN protocols, or set of standards used to establish a VPN connection.

IPsec VPNs come in two types: tunnel mode and transport mode.

What ports does IPsec use?

By default, IKEv2 uses IPSec, which requires UDP ports 500 and 4500, and ESP IP Protocol 50. You cannot disable IPSec. By default, L2TP uses IPSec, which requires UDP ports 500 and 4500, and ESP IP Protocol 50. If you disable IPSec, Mobile VPN with L2TP requires only UDP port 1701.
