I just did an upgrade from 6 to 7 which went surprisingly well just one little niggle is that I had multipole WAN using PCC which worked fine and the secondaries which interface with other routers seem to be ok now but the primary which established its own connection via PPPoE can seem to check its gateway any longer, I think this is down to the new routing table or maybe it no longer an option to check dynamic interfaces?
Can anyone help?
