Does the Mac VPN client work through a router or an Apple airport?

The router must allow data through port 500, protocols 50 and 51, and allows any UDP port to be used for NAT traversal. For example, the Asante FR1000/3000 series routers are not End Point solutions, and does not work with the Netlock VPN client; whereas, the Asante VR2000 series should support it. In general, the EVPN solution is using NAT Traversal over port UDP/4500. This information is in the LM EVPN FAQs. Be sure to keep the firmware current. The ability to use the Client with the AirPort is dependant on the model and firmware version of the AirPort being used, whether or not the AirPort is acting as a NAT device, and whether or not NAT traversal is configured on the Contivity switch. Early models of the AirPort do not support IPSec passthrough or NAT traversal. They will not work with the Client when it is used as a NAT device. These models of AirPort will only work when the AirPort is co
