Or just enable RIP and do some of the below.   Or...use a router for a
router...and an AP for an AP. ;)

You create direct routes for those net works on interface 4.  So 174.18.4.1
and 5.1.  All the clients and KN-50's point to their respective gateway, the
5.1 or 4.1.

Then on the Ethernet interface of your TC base, you set it to 174.18.0.10,
again a direct route.

On your upstream router, of course it must have an ip, if only a secondary,
on its interface... let's say 174.18.0.10.  And then you make a route on
that device for the .4.0 and .5.0 nets to the 174.18.0.10.
Set NAT pool access list to allow the 174.18.0.0 0.0.255.255


And there you be.
If you want to give customers a public network inside their SOHO router.
Then you add a route on the upstream router to the 174.18.0.10, and then an
indirect route on the TC Router to the IP of their wan port, in this example
174.18.5.2 being the first customer.   Then assign the public network to the
LAN interface on their SOHO, and turn of NAT, and they have public network.

I also had problems with the older Karlnet firmware versions and routing..
some screwy thing about the device not wanting to route for different
subnets.. but it's fixed in V4.

Ok, routing champions, say I've got a bunch of 174.18.5.X clients (the WAN
IP of their routers) off radio interface #4, the radios (bridges, all
KN-50s) at 174.18.4.X, and the Ethernet (#1) interface is looking back at
the border router which is NATing all the 174.18.5.X clients from
174.18.5.1.   How would I set up the routing on this AP to make this work?
