Cisco 2811 Voice Router - Block Statics

I have a cisco 2811.  In FA0/0 I have my DSL modem plugged up.  The DSL modem only has one Ethernet port on it.

I am trying to pass back the static block to multiple devices.

So Device 1 has the first static and Device 2 has the second.

How can I accomplish this with one ethernet port?  Should I create sub interfaces as vlans and assign the static IP addesses to the sub interfaces?

This is what it looks like right now - Numbers changed for privacy.

Thanks for that.  I know how to pass vlans as sub interfaces.  My question is does ISP addresses work the same way?

Yes, any IP's work in similar fashion isp/lan does not matter.

But router-on-a-stick will not be a good method then.

In your scenario, I would have used public IP's natted to internal lan IP's. You do not need any such primary/secondary then. Just put static nat's of public IP's pointing to internal lan IP's.........
