I read in the guidebook that I have to enable port forwarding. I got so in the settings area to the port forwarding, I added the ports as provided in the guide: L2TP/IPsec UDP 500, UDP 1701, UDP 4500 Here's an example of the configuration. I put in the IP address the ip of NAS.
May 24, 2019 · L2TP (Layer Two Tunneling Protocol) is a combination of the Point-to-Point Tunneling Protocol (PPTP) and Layer 2 Forwarding (L2F). While PPTP only establishes a single tunnel between two end points, L2TP supports multiple tunnels. IPsec is often used to secure L2TP packets by providing confidentiality, authentication and integrity checks. Port Forwarding allows you to make a device or service in your home network accessible by other devices over the internet, whilst ensuring your network remains protected. Different services use different service ports, such as Port 80 for HTTP service, port 21 for FTP service, port 25 for SMTP service and port 110 for POP3 service.

I put in the IP address the ip of NAS. Specify the protocol and port details for the traffic that is being forwarded in the "IP Protocol" and "Port" fields. Select the WAN interface to apply the rule to and place a checkbox next to the target WAN IP in the "Inbound IP Address(es)" field. Specify the IP address of the LAN device to forward the traffic to in the "Server IP Address" field. Jul 18, 2016 · Now this new port forwarding rule can be leveraged, and it can be pointed at the Synology. In the “tab bar”, choose Firewall Settings and then, on the left, Port Forwarding.

L2TP Port Forwarding I have a MacOS server (running High Sierra) on my office network that also acts as a VPN server. Previously, VPN was working perfectly, occassionally, there would be issues, but a router/server reboot would fix things.
If you are using one or more of the WAN IP Addresses for HTTP/HTTPS Port Forwarding to a Server then you must change the Management Port to an unused Port, or change the Port when navigating to your Server via NAT or another method. The following walk-through details allowing HTTPS Traffic from the Internet to a Server on the LAN. I am trying to use it as my VPN, but when I set up port forwarding on the router I am not having any luck. It appears that I am forgetting something. I have tried ip nat inside source static udp 192.168.xxx.xxx 500 interface Fa0/0 500 for all three ports (500/1701/4500) needed for L2TP, but I cannot seem to connect. Any advice would be appreciated.

Previously, VPN was working perfectly, occassionally, there would be issues, but a router/server reboot would fix things. 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. 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). Routers without these options may not support PPTP or L2TP traffic To allow PPTP traffic, open TCP port 1723; To allow L2TP w/ IPSec traffic, open UDP ports 500, 1701 & 4500 Protocol: UDP, port 4500 (for IPSEC NAT-Traversal mode) Protocol: ESP, value 50 (for IPSEC) Protocol: AH, value 51 (for IPSEC) Also, Port 1701 is used by the L2TP Server, but connections should not be allowed inbound to it from outside. There is a special firewall rule to allow only IPSEC secured traffic inbound on this port. source.
