Ah Thanks will look into that, hopefully get something working this evening/weekend.
Edit: Running it, although I ended up hardcoding the routing rule id as the find by comment code I had working vanilla netwatch didn't seem to work, I have a rather aggressive (5s) schedule going on so hopefully that's not going to cause excessive flash writes, using IP's rather than DNS names.
Edit2: Kicking myself a bit, easy way to solve the problem of finding the rule ID is to create a script to do that and run it from up-hook
