VPN Client 4.0 to PIX - Notify with invalid protocol id (0)

[chiphead24]

VPN was working until moved PPPoE from PIX to ISP gateway. Removed PPPoE config lines. VPN client log gives me:

3 09:38:59.616 06/29/06 Sev=Warning/3 IKE/0xA300004B
Received a NOTIFY message with an invalid protocol id (0)

Here's my PIX config.
