Re: Configuring Wireless ISP
You've got mismatched subnets. It might work with some hacking, but you're better off designing it correctly. Does the Linux box route? If not, you'll need to have a common subnet at least from the Cisco router to Radio1, and you should insert a hub or switch to tie together the data path from the Cisco router to Radio1. Do the radios route, or are they just L2 bridges? If they are just bridges, you'll need to have a common subnet from Client Box to at least the Linux Box, and possibly all the way to the Cisco Router if the Linux box doesn't route. If they route, they'll need two IP addresses, one for each subnet. Basically, anywhere you have a L3 device (i.e. router or multihomed device with routing capabilities enabled) you'll need to separate your subnets. Also, don't use the term class C.
