I'm a consultant with several small accounts and two large ones. Both of my large clients have Cisco network equpment and provide access for me to their corporate resources using a VPN.

With client one, who use a Cisco 3000 series appliance, the IPSec connection is over TCP and it works like a champ. Client two, a large technology company, uses a Cisco 7000 series router and provides IPSec over UDP. That connection seems to time out after about 15 minutes. I've talked to the companies internal Cisco guy, and have had long conversations with a router SE at Cisco. There claim is that UDP is an "industry standard" and that because most hotel networks and access points provide services through NAT/DHCP, there is no way to reliably connect to the VPN. This sounds like an excuse to me.

Any traveling net geeks amoung the faithful who can offer advice on this one?

Regards,
Dave
