VPN - Problem with NAT firewalls.
November 26th, 2007 | by programming |The popularity of telecommuting is increasing and this is why companies have been turning to Virtual Private Networking (VPN). The problem is that not all of them have made it easy by using “NAT friendly” VPN gateways and VPN clients. Most of them require changes to home users’ router settings in order to successfully set up a VPN tunnel.
There are two easy ways to make your VPN client work:
a) Some routers have PPTP or IPsec “pass through” setting.
b) You can set port forwarding for tcp port 1723 and udp port 500.
After resetting the router, your vpn connection should work perfectly.
