If your internet router supports VLANs using 802.1Q, then configure it up as
a router.

You need to be careful that you dont:
break security if the customer doesnt route between VLANs
carry all the inter VLAN traffic if they do route.

a more important Q may be - why not use their inter VLAN connections?

very messy, and you should only need 1 box.

a reasonable router should be able to do this

if there is little traffic then maybe a cisco 17xx with the right WAN
interface, VPN accelerator if you need it and IOS plus to allow 802.1q
subinterfaces to route between VLANs?
