Ok, which ports are the correct ones for IPSec/L2TP to work in a routed environment without NAT? i.e. I want to use the built in windows client to connect to a VPN behind this router/firewall. Perhaps a good answer here is to specify which ports to open for different situations. I think this would be useful for many people.

VPN clients use encrypted VPN tunnels to ensure the privacy and integrity of the data passing over the public network. Cryptographic controls are exercised in compliance with the IT Act enacted in the country. For IPSec VPN, the following ports are to be used: Phase 1: UDP/500. Phase 2: UDP/4500. Below is a list of some common VPN protocols and the ports that they use: PPTP (Point-to-Point Tunneling Protocol) – This protocol uses port 1723 TCP. L2TP (Layer Two Tunneling Protocol) – This protocol uses port 1701 TCP, Port 500 UDP, and port 4500 UDP. Our VPN service uses these ports for Firewall configuration: For OpenVPN, we allow connections via TCP or UDP protocols on ports 443 or 1194. The IPVanish software uses port 443; Both PPTP and L2TP need the PPTP & L2TP pass-through options in the firewall/router's management interface to be enabled (if applicable).

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). IPsec uses cryptographic security services to protect communications over Internet Protocol (IP) networks. It supports network-level peer authentication, data May 20, 2003 · IPsec-based VPN’s need UDP port 500 opened for ISAKMP key negotiations, IP protocol 51 for Authentication Header traffic (not always used), and IP protocol 50 for the "encapsulated data itself. There are several different ports listed when you Google this topic. In practice I have found that I only need to open UDP 500 and UDP 4500 in order for VPN to work. Protocol: UDP, port 500 (for IKE, to manage encryption keys) Protocol: UDP, port 4500 (for IPSEC NAT-Traversal mode) Protocol: ESP, value 50 (for IPSEC) Protocol: AH, value 51 (for
If you decide to use non default VPN Ports (i.e. UDP 500 & UDP 4500), the destination router (i.e. at the edge of your corporate network) must be configured to reroute the incoming traffic associated with the new selected VPN ports onto the default UDP 500 & UDP 4500 so that they properly routed to the IPSec service.
IPsec VPN with FortiClient. In this example, you allow remote users to access the corporate network using an IPsec VPN that they connect to using FortiClient. The remote user Internet traffic is also routed through the FortiGate (split tunneling will not be enabled). Used for IPSec tunnel connections between GlobalProtect apps and gateways. For tips on how to use a loopback interface to provide access to GlobalProtect on different ports and addresses, refer to Can GlobalProtect Portal Page be Configured tobe Accessed on any Port?
