L2TP over IPSEC default gateway - stopped working

Hi - I have a demo software installation going. If it works out, will likely go with a UTM110 with the new license scheme (given terribly slow DSL uplinks).

Background -
- 2 uplink interfaces (DSL - they have a high failure rate, so redundency)
- Uplink balancing enabled
- 3 internal VLANs (phone, company 1, company 2) (each has DHCP, 2 have NTP enabled)

I am trying to use L2TP over IPSEC remote access and it was going well. It suddenly stopped working. I have been making lots of changes, so it is likely something I did, but can't figure it out.

After I connect from my remote windows7 machine, the remote machine can't access anything. I watched the firewall/IPS logs and see nothing interesting.

I did notice that ipconfig on the client is showing 0.0.0.0 as the default gateway for the VPN connection. The client VPN address is 10.242.3.2.

Is the missing default gateway the problem? If so, why is it missing. If not, what else can I look at?

Also, regarding the HTML5 VPN - sometimes it works, sometimes times out. Nothing noticeable in the logs.
