• plan for code that is easy to delete/replace rather than code that is easy to extend or reuse. As needs change, you're more likely to change the assumptions about what the system should do than in how many ways it should do it. If the code needs extending, it's then easy to replace it with a bit that's easy to extend
• planning for code that is easy to throw away is the best way I've found to properly bake in abstraction and isolation. The question is always "if I take this shit out or change its implementation entirely, do I need to replace anything else?". If the answer is "yes", then you may be leaking into other components. Fix it. turns out when you have that, it's also suddenly easier to reuse code.
• write a prototype of whatever significant task you have to do, and consider it a draft. Use it to figure out requirements or to make your first mistakes in. Throw it away. Try again. As I gain more experience I find my prototypes smaller and individually more solid, but anything where I lack experience t

I'm using [PORT]net/zerotier[/PORT] for quite some time as a way of getting to my systems from other networks very happily. It works in airports, cafes, and all the usual hostile places we travel to.

It provides a L2 encrypted mesh (a bit like VXLAN I suppose) via a tap interface.

What I'd like to do is to use the ZT network as a VPN - routing all traffic from my FreeBSD laptop and phone through the zerotier layer out to my appointed ZT "VPN Gateway". Basically, translating the linux doc here: https://support.zerotier.com/knowledgebase.php?entry=show&search-for=full&article=ZWFhNWMyMTZjODY1ODcwNmFhZmJjYmRhN2I5MjRhOGQ_ -- into FreeBSD config. BTW https://www.zerotier.com/manual.shtml has a lot of background detail if you're interested.I can get the iphone working, but not the laptop.

What works after configuring zerotier to provide the "default route" is different on each device:

• the iphone works
• an apple imac works
