Wow! Thanks for your reply, this did it !
I guess I had too much going on and it was quite a simple fix.
For some reason
dhcp-option=tag:belldns,dns-server,207.164.234.129,207.164.234.193
didn't work with dnsmasq-test, it would say "bad syntax"
I changed it to
dhcp-option=tag:belldns,6,207.164.234.129,207.164.234.193
and it works! Thanks a lot, this is resolved!
Thank you
