It's not an issue of expense it's simply the correct router for the new
connection.

For 2 or 3 PCs or just the 1? BY accounts unless business or otherwise
are a single DHCP IP. So with 1 PC it works.

So no need to change this as you did then.

It does, in fact there are several MAC addresses and IPs as there are
several interfaces.
It's been a long time, since I last looked at this. There is an internal
to BY 172 address, the your LAN 192.168.100.1 (something for the
internal webserver) the rest of that range for it's DHCP and then at
least a 3rd is the pass through of the public 82.x.x.x public range.
Then the usual router webpage 192.168.0.1, or similar.
The Webstar to the router (routing processes) handles things for you.

Got that, that's why you need a broadband ethernet router.

Don't go there, you really want to risk using the address of another
user? The ISP will give you a helping hand with that one.
The IP address of the router (WAN port is the ISP DHCP address, it's the
1 device / interface connected to the ISP) is less of an issue using
only the LAN ports and not using the correct model for a broadband
ethernet connection.
If you add a 2nd PC to another LAN port I would expect it not to work.
The 1 PC when it does work will have the ISP assigned IP, add a 2nd PC
and check what happens to the 1st by comparing the ipconfig/all output.
That's not a LAN or WAN connection routing at that point, just the 4 LAN
ports ascing as a shared connection.

You are going off course here. You need to get the correct type of
router and all the isues go away.

As they do, remember it's only meant for 1 device. Sharing / ROuters
aren't supported however much they are allowed.

( I haven't tried this as I manage with an wireless access point plugged
into my router and the wireless link to a wireless router. The router is
either an extension to current LAN 192.168.0.x or a totally different
192.168.2.x and setting up RIP to exchange routing info)
- Is get a cheap single port wireless access point plug that into the
webstar as the ISP device. The AP feeds the ISP IP to a laptop. Just
tried it for fun.

Range Extender/AP , wireless to Dell 1501. Works fine.
