Hi:

We are testing Vista 32bit laptops with SecureClient NGXR60HFA02 (without the recently released Security Hotfix 01) and Verizon EVDO REV A PCMCIA aircards on Lenovo Thinkpad X60s, X61s, and T61Ps.

About 10-15 seconds after the VPN client is connected, the Verizon software reports 'Network Disconnected' and the VPN client disconnects. If I reconnect, the IP address has changed and SecureClient is similiarly furious. I've also tried NDIS mode with the aircard, and same behavior. The aircards work fine with the VPN client running and idle, just not when we build the tunnel. Wifi and wired Ethernet works fine, with and without VPN. We are able to maintain a tunnel when connected to a Linksys WRT54G3G-ST (EVDO to ethernet/wifi bridge/router), and the Verizon cards work fine on our standard XP SP2 builds.

I'm able to reproduce the same behavior using SNX to both a Connectra and a R65 gateway. We hand out 172.x office mode IPs everywhere, so that is the only commonality I can think of so far. When connected to the Verizon network, we do get a routable IP address.

The Secureclient logs show something interesting:

Interface change: PANTECH PC Card WWAN Controller removed

Session drops. Then, 30 seconds later:

Interface change: PANTECH PC Card WWAN Controller interface added, current ip: 169.254.14.242

User Desktop Security Policy Loaded

Interface change: PANTECH PC Card WWAN Controller interface IP changed, previous ip: 169.254.14.242, current ip: 75.xxx.xxx.xxx

So, it looks like something is causing the interface to get removed shortly after the VPN session is established, and re-added after the VPN session drops.

Any ideas?
