VPN Authentication Problems on Wirless Network


I am taking a shot in the dark that someone here can help.
I am new to IBM and having difficulty getting the ATT Global Network
Dialer (VPN) to work over my wireless system.
If I Right Click "My Network Place" and go to Properties and "Right
Click" on both my AGN Virtual Network Adapter and Wirless Network
Connection - shut off "Net Firewall Service", reboot and then turn the
service back on - I can log in my VPN - *But only once*.
If I then diconnect, and try to reconnect I run into the same problem
where the VPN cycles through trying to authenticate over and over
again.
I am running through Bellsouth DSL with a 2WIRE DSL Modem and Wirless
Router. The T41p Thinkpad is picking up the 11b signal at good to
excellent strength.
Currently under the VPN Configuration I have two odd things checked in
the "Misc" section:
1) Negotiate UDP Encapsulation with VPN serverfor NAT Transversal
2) Authenticate via HTTP for IPSec
3) MTU is set at "Default" which is reccomended. I did some basic
pinging w/o fragmentation loss at 1464 when I was playing around last
night.
I set up my own home network and know enough to make me dangerous, but
in no way am and expert - so any help would be appreciated.
Thanks in Advance

I have been working with customers who are current SBC Global DSL customers. I was recently told by a 2 Wire Tech that protocols 50 and 51 were not supported on these routers and would not pass through. Terminating a VPN behind this equiptment would not work. In these case I have been. Purchasing vanilla DSL modem from local tech shop. Placing VPN capable router ( we use Cisco equiptment) behind modem and terminating PPPOE.

Hamachi is a peer-to-peer VPN system which uses their directory server to find the end points. I'm not thrilled with the security implications of requiring the use of their "backend" servers:
