can a domain name config point to a vlan tag at the host

[Ernie Luzar]

I set up vlan for the host interface cabled to the public internet.
How do I drive internet traffic to the desired vlan name on the host 
using a registered domain name?

My rc.conf has this

ifconfig_re0="DHCP"
gateway_enable="YES"

vlans_re0="1 2 3"

# vlan_1  is for the host
# vlan_2  is for vnet jailA
# vlan_3  is for vnet jailB

Final goal is to drive traffic from the public internet using a fqdn to 
the vnet jailA.
