I managed to fix most of my VPN connection issues by updating the security settings in the SuperHub to allow IPSec, PPTP and Multicast pass through. But, I still have one problem relating to a document management agent we use. Its just not recognised and won't connect. It seems to be a problem I only have with my home SuperHub (works everywhere else, even on public wifi).
Are there any other quirks of SuperHub that could cause this type of issue?
