Ah, the good old DMZ. Where IT pros send all their problems to live in isolation. Option B it is!

Option C looks like it could open up your network to potential attacks. I'd rather not take that risk and go with the firewall-friendly option B.

Haha, option D sounds like a classic IT compromise - 'it works, so let's just roll with it!'. I'll go with the more secure option B.

Option B seems more accurate. Exposing ports directly to the internal network can be a security risk, so I would expect the Mesh Node in the DMZ to handle that.
