I use PBI but on the cheap plan with PPPoE.
My setup is:
ADSL Bridge (Westell WireSpeed)
|
|
eth0
Firewall/Router
eth1
|
|
Local Area Network
192.168.1.0/24
You can probably "abandon" the other IPs. I'm sure if you wanted to you might
be able to set up some forwarding rules that could pass stuff through the
firewall (from certain public addresses to specific private addresses) while
blocking all unwanted traffic, i.e. only letting web, email, (incoming)ftp, etc.
something along the lines of:
64.1.1.1 <-----> <-----> 192.168.1.2
64.1.1.2 <-----> <-----> 192.168.1.3
64.1.1.3 <-----> Router/Firewall <-----> 192.168.1.4
64.1.1.4 <-----> <-----> 192.168.1.5
64.1.1.5 <-----> <-----> 192.168.1.6
Basically the thing that is different from your set-up is that the firewall
and router are the same machine.
Since PBI abandoned the single static IP, people wanting
static IPes are forced to pony up the extra money while not needing the extra 4
addresses. They seem to allow you to do whatever you really want to with the
line. I know they tried to push the 5 IPs on me while ordering (I did mention
the LAN), but with the Enhanced they really shouldn't have a problem.
I have seen various fire walling scripts floating around on the list. I adapted
one from rp-pppoe client.
