Probably true, but the lappy I bought for while I was out playing 
consultant after I retired, which put me in a motel or the owner guest 
house for months at a time for several years, is now quite aged and 
hasn't been powered up in several months for anything but updates to its 
mint 15 install.  So I could be the exception to that "rule".

And in turn that cheap plastic consumer grade router no doubt has an NSA 
back door clear into the smallest machine on your network.  My router is 
a plastic buffalo netfinity, paid about $70 for it and it has been 
reflashed with the real dd-wrt, not the version that it came with, which 
among many other features has a dhcp client to get its address from my 
isp, but it also has a server that can if configured to do so, hand out 
200 some leases.  It also has no back doors for the NSA, and in 15 years 
of running dd-wrt on 3 different pieces of hardware, has had only one 
person come thru it and I gave him the username and pw to do so.
Lots of features I don't enable are there. Port forwarding is one, you 
can see my web page (in the sig) which I run in a sandbox on this 
machine.

I'll have to plead ipv6 ignorance as the nearest outside ipv6 is at least 
100 miles away from me. My questions as to how to enable it between the 
10 or so ipv4 addresses available here if everything is booted up, have 
been ignored. I don't know if the first of two switches I have here even 
passes it, and haven't seen a "getting started with ipv6 for dummies" 
tutorial, if it even exists.

I suspect it will arrive here after I've not made morning roll call for 
several years.  So like a jar of pickles I found while cleaning out the 
veggie drawer today, its been shoved to the back of the bottom shelf. :)

But you should get yourself a real router, and reflash it with some real 
router firmware, dd-wrt, tomato or one of the other lesser known router 
firmwares. dd-wrt is bulletproof to the point I don't run iptables or 
its ilk on the machines of my local network.  Don't need it.

You too, David.
