Hello Friends,
If anyone knows the process of troubleshooting VPN passthrough for home routers, please tell me. I am facing many problems with my VPN. |

Hello Nicole Smith,
Any of these steps may solve the problem:
1. If your equipment supports NAT-T (NAT Traversal), turn it on.
2. Contact your network administrator to understand details of how you need to configure your VPN software. (Common software is Cisco NAT-T and NETGEAR ProSAFE).
3. If your company uses L2TP passthrough, register your router's MAC address with your company's system administrator.
4. Upgrade to the latest router firmware.
5. Enable Port Forwarding for the VPN port 500, (for IPSec VPN's), port 1723 for PPTP VPN's, and port 1701 for L2tp- L2tp routing and remote access. Port 500 may be listed under the list of services.
Note: Check if the WAN IP is public or private. Ports can be opened on Public IP addresses only.
6. By default the router's firewall is configured to drop (delete) ICMP packets sent from outside your network to the WAN port. Your VPN may require the ICMP packets. To accept them:
a. Log in to the router using a browser by typing http://192.168.0.1, http://routerlogin.com, http://routerlogin.net or http://192.168.1.1.
b. Type admin for the username and password for the password (unless you change the password from the default).
c. Select WAN Setup > Advanced > Respond to Ping on Internet Port.
d. Click Apply.
