SSTP VPN

I just setup SSTP. When I log into the portal and click on SSTP a connection is established, I get an IP address from DHCP, the assigned address is from the same scope as the internal IP address of the UAG server.

So now what? I can't ping anything internally or access anything over sstp? I want to be able to access resources, i.e., internal sites etc... like I can with normal VPN.

Any ideas what I'm doing wrong?

Thanks
