I see IPv6 traffic coming from it (I believe) but there's no IPv4 response .I should see if I can set up my Linux machine as IPv6 and see if I can access any of the services there. IPv6 is new terrain for me so helpful pointers would be quite welcome.

make more sense. on my "stock" cerowrt box my My routing table looks
like below. I don't get the line for 172.3.42.0/24 with the flag of '1'
and an asterisk for the interface.

Yes, my work network has lots and lots of test subnets.
Since I can hit any of my work networks from the 3800 but not from my
lan, I suspect I'm missing some firewall rules.
one important question: Is there a way to define a named constant or
indirect reference to value in UCI instead of the literal.
dhcp: option ip '172.30.42.1'
network: option 'ipaddr' '172.30.42.1'
becomes
dhcp: option ip @internal_gateway
network: option 'ipaddr' @internal_gateway
and internal_gateway is defined on one place
