Symantec VPN error connecting

Error connecting tunnel to The server rejected the ISAKMP security association. Make sure the phase1 IDs, shared key, and IKE policy are correct. Terminating connect operation.

I am using Client to gateway VPN.  Symantec Gateway 320.  On home side I am using sbcglobal with a 2 wire DSL connection.  I have a wireless network but am connecting directly to modem to do this because of subnet conflict (If you know how to fix this it would also be helpful).  I was able to connect for a long time when I had cable, but now switched to SBC and got the following error.
