IPSec: for the IPSec VPN tunnel, set the local port to 500 and protocol to UDP, and port 4500 with UDP protocol for the IPSec tunnel. OpenVPN: local port set to 1194 and protocol to UDP. IKEv2: this needs the port to be set to 500 and protocol to UDP; You can now set up a VPN connection on another computer by using the public IP of your VPN server. Port forwarding is a technique used to enable incoming internet connections to reach your device when using a VPN. It is necessary because most VPNs use an NAT firewall to stop users falling victim to malicious incoming connections. If you are setting up the firewall to work with a peer that supports policy-based VPN, you must define Proxy IDs. Devices that support policy-based VPN use specific security rules/policies or access-lists (source addresses, destination addresses and ports) for permitting interesting traffic through an IPSec tunnel. There are no other pre-existing L2RP/IPSec port forward rules or otherwise conflicting port forward rules (e.g.: another rule for ports 500, 1701 or 4500) There was an L2TP port triggering rule enabled, that I toggled on and off with no change; Verified the firewall on VPN server had an exclusion for L2TP, or that the firewall is off. Yes. A test (or demo) VPN Configuration is VPN configuration designed by TheGreenBow Techsupport team to connect to our online IPsec VPN gateways and servers. Those are always live and you can use it to test your network environement at any time. This test VPN Configuration is specific to our IPv6 ready IPsec VPN Client 6.0 and further.

The process of setting up an L2TP/IPsec VPN is as follows: Negotiation of IPsec security association (SA), typically through Internet key exchange (IKE). This is carried out over UDP port 500, and commonly uses either a shared password (so-called "pre-shared keys"), public keys, or X.509 certificates on both ends, although other keying methods

Thanks all for the help. I was mistaken about the protocol number and the port number. The device I was talking about is 3700 and 3800 series routers. I need to establish IPSec between them. Can someone give me an example of the ACL to allow the protocol numbers mentioned above? I've never used NAT-T, is there an example of using it? Thanks a ipsec vpn ports? - Cisco Community Re: ipsec vpn ports? Most likely not possible on an ASDL modem and since he is doing NAT the solution would be as stated above to use NAT-T.
