First off, what protocol of VPN are you using? OS X Server offers both L2TP (over IPSEC) and PPTP protocols, both of which use different ports. For L2TP you need ports 500 (UDP), 1701 (UDP), and 4500 (UDP). Forward these ports to the same ports internally. For PPTP, it would be ports 500, 1723 (TCP), and 4500, also forward the same internally.
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. Therefore pushing phase 2 up to udp/4500. Nov 25, 2013 · Synology L2TP/IPSec VPN In the last few releases, Synology has added L2TP/IPSec as an option for a VPN. I’ve never been able to get it to work on a Windows client until today. UDP 1701 - L2TP. ESP/IP 50. AH/IP 51. Mac mini Server: has static IP address. is the DNS server for the network. is (of course) the VPN server with the configuration as follows: setup for: L2TP only. VPN hostname: public IP address. Shared secret: dull-8caracter word. Addresses: 10 for L2TP x.x.x.200 up-to x.x.x.209. Name server: Microsoft RRAS server and VPN client works with PPTP, L2TP/IPSec, SSTP and IKEv2 based VPN connections. The PPTP control path runs with TCP, and the data path goes with GRE. The L2TP tunnel traffic is rendered over an IPSec transport mode, and the IPSec protocol has an inbuilt control path that moves through IKE and data path over ESP. What is L2TP? L2TP stands for Layer 2 Tunneling Protocol, and it doesn’t provide any encryption by itself. L2TP VPN usually uses an authentication protocol, IPSec (Internet Protocol Security), for strong encryption and authentication, which gives it an ultimate edge on some other most used protocols like PPTP. The L2TP protocol uses UDP ports 7. Right click the recently created adapterfor L2TP VPN and choose Properties. 8. Navigate to Security tab, choose the Type of VPN as Layer 2 Tunneling Protocol with IPsec (L2TP/IPsec) and then click on Advanced settings. 9. Enter the preshared key as the same mentioned in tunnel-group DefaultRAGroup and click OK. In this example, C!sc0@123 is
An older Linksys router calls it "VPN Passthrough," but it only supports PPTP, unless there was an update that provides it (I'm not 100% familiar with all their versions). A newer Linksys supports both L2TP and PPTP, and referes to it as "L2TP Passthrough," or "PPTP Passthrough", and this also depends on the model# and versions.

How to Set up an L2TP/IPsec VPN Server on Windows. In this tutorial, we’ll set up a VPN server using Microsoft Windows’ built-in Routing and Remote Access Service. To do this, we’ll be using the Layer 2 Tunnelling Protocol (L2TP) in conjunction with IPsec, commonly referred to as an ‘L2TP/IPsec’ (pronounced “L2TP over IPsec”) VPN.
R7000 Ports for L2TP VPN I have a customer who has an existing R7000 / AC1900 set up in Firewall mode. The customer does not want to change to AP mode due to reaching the limit of IP addresses in his subnet and does not want to expand his subnet.
