Mike and Jason, i'll send you out an email.
And to all, yes, i'm aware of the downsides of mine and others solutions. This is an outbound connection which is probably not liked or even allowed on businesses.
I've developed this more for residential clients or some corporate clients but where my gear is off-network (we have our own stand-alone network disconnected from everything else, including internet).
I also agree that for corporate you/we have to sit down with the IT dpt and figure out the best way to deal with it.
I have a customer where the only option is to go fisically there. Then another where our gear is on a vlan similar to the guests network which has internet but isolated from corporate data.
Etc.
Anyway, i'd be happy to learn better ways and also how to face corp clients.
Cheers!!
