Our Internet is provided remotely from our property - since we're much too far from any wired Internet connection.

We have a remote location for a separate phone line and a router - connected to the ADSL (and running DHCP) that is connected to one Wireless AP. The signal then does a series of 'hops' to various locations covering 9 miles in undulating terrain using connections provided over 5Ghz Wireless AP's. We get the signal after 4 intermediate devices.
Currently static IP's are used: 100.100.50.1 being the router and then 100.100.50.5, 100.100.50.10, 100.100.50.15, 100.100.50.20 being the AP's.
The cable from the last AP (100.100.50.20) goes into a 'local' wired/wireless router that currently acts as a bridge - and everything in the 'local' network connects to that router on the same 100.100.50.XX IP range and subnet - with the IP assignation (for anything that's not static IP) DHCP being covered by the router at the ADSL connection.

The issue is that now we've got the network working well and it's reliable - I need to keep the 'supply' network separate from the 'local' network and not have all the internal and 'local' traffic routed remotely as I think it will slow things up having to hop all the way down to the remote router to get routed.... Security could also be an issue... :no:
We only ran it as one network to see if we could cover the 9 miles and get a decent speed/ping. We can.

What do you think is the best thing to do now?

How can I best set up the second router? As a second network inaccessible from the 'supply network' and using 'local' DHCP - keeping the two networks separate?
The only time I'll need to get on to the 'supply network' is when we have a problem or admin is needed on the AP or a remote reset of the ADSL modem...
I can easily use a switch or something at this end to allow a hardwire connection to do that.

Since IP addressing, subnets and the like are not my strong point - please give detailed advice... Thanks.
