Two networks: 192.168.1.0/24 and 192.168.10.0/24. Call them .1 and .10. Dot 1 is *not* in a VLAN.
Dot 10 is associated with VLAN 10.
The problem is I cannot get traffice between 1. and .10 (and vice-versa). I've tried many different
configurations --the results you see below and the attached configuration is the case study. I've
set this up, taken it down several times to be certain.
A DHCP client in VLAN 10 *CAN* get an ip address in .10. I've done this repeatedly. I've also set
and unset "vlan aware" and the "vid" for switch0 just be sure VLAN tagging is working.
There are no firewall settings between .1 and .10. I'm under the assumption this isn't necessary.

switch0 = 192.168.1.254/24
VLAN_10 = 192.168.10.0/24
192.168.1.5 <-> 192.168.1.254

192.168.10.10 <-> 192.168.10.0/24
<-> = OK
<!> = NOT OK
I've tested the connectivity noted here with ICMP and several TCP ports.
