We are having strange issues.. Here is a rundown of the layout:

<internet>---<isp network/router>---<switch>---<local-aib>---<remote-aib>---<PC>

The network being used for the wireless link is as follows:

64.42.139.48/29

ISP Wireless Router - .49
Local AIB - .50
Remote AIB - .51
Remote PC - .52

ISP Router is just a gateway router for multiple 802.11b links we have.
Its on a much larger network local to the ISP (us). The link above is
our first and only link using AIB's. We are having issues where
machines/devices on the ISP Network side are having trouble pinging the
Remote PC while other machines/devices on the SAME SUBNET (local ISP
Network) as the machines/devices having trouble are not.

For instance,

Plato (our shell server), is 64.42.128.47/27
NS (our name server), is 64.42.128.50/27

They are in the same subnet, off the same router interface and switch.
Plato can ping Remote PC but NS can NOT.

If we reboot the Local AIB the issue goes away, but the next morning (or
a few hours later), the issue is back. My first guess is the routing. I
triple checked everything I can think of. I am very confident the
routing is correct because no other wireless customers (fed off the same 
ISP Wireless Router) don't have trouble reaching the same destinations
that the AIB link is having trouble with. Also, traceroutes are showing
the correct path, only from the machines having trouble (ie, NS) the
traceroute stops AFTER leaving the ISP Wireless Router, and traceroute
FROM Remote PC never even make it to the ISP Wireless Router. Almost
like the packets are dying between the Local AIB and Remote AIB, yet
from Plato its absolutely fine.

My next guess is the 64 client limitation. My question is this... Would
the AIB's hold a "client table" of IP addresses requesting data through
it, say to Remote PC, and use this table as its 64 allowed clients? Keep
in mind most of the "Source IP's" are NOT in the AIB's local subnet (I
doubt that this matters). If so, would this by the cause of the issue I
am experiencing?

Thanks for any and all help you may provide.
