If the Cisco VPN server is a Cisco VPN concentrator, you need to check the
"NAT-T" box.
If it is a Cisco Pix firewall, it needs to run at least version 6.3(x) to
support nat-t. The command on the pix to enable nat-t: "isakmp nat-traversal
20"
Furthermore, you will also need to allow udp port 4500 outbound in addition to
isakmp udp
500 as well.
Good luck.
