Gah - whilst trying to help out a friend, I inadvertently modified the firewall rules to lock everything out while I was working remotely. Long story short - when flushing the firewall rules, set the default policy to accept unless you have physical access to revert to working config! Otherwise (like today) you not only lock out intruders, you take out your connection you were using to manage the firewall, and can't reconnect to fix it!! DOH! Apologies to all. (See, even us über nerds get it wrong occasionally!)
