|Question / Issue|
|VPN Client works from home but not from office|
|Answer / Solution|
The Proxicast VPN Client for Windows can make a VPN connection to a LAN-Cell from a home or mobile Internet connection, but not when installed on a PC on a corporate network.
When using the Proxicast VPN Client behind a corporate firewall/router you may need to enable the NAT-Traversal (NAT-T) feature of the VPN to handle the network address translation that the corporate router is performing on all traffic.
Beyond NAT-T, the corporate firewall must enable traffic on the standard VPN ports: UDP-500 for IKE, UDP-4500 for NAT-T as well as permitting ESP traffic for the IPSec Tunnel itself. Most firewalls permit these outbound connections by default.
|If I create a VPN tunnel, do I also need to create NAT and Firewall rules?|
