ive seen this when you have 'bridging' ticked. Untick it, along with
'routing' in general setup when you are running with this setup.

Subject: [Karlnet] Problem with RG-1100, SR-4200, running NAT
We service two very different cities: in one of them we perform
routing at every stage of the wireless game, but we don't use NAT or
firewalling at the customer premise; in the other city we bridge
everything wireless and have to use NAT on the CPE.
We have been using RG-1100s with the SR-4200 (Satellite) image in the
routing city for quite some time, always with great success. We have
recently begun rolling out the same hardware/software for the CPE in
the bridging city, obviously configured differently to match the
different network circumstances.
Every installation (and there are quite a few) of the RG-1100/SR-4200
combo on the bridged network has had the same problem. We configure
NAT as directed in the KarlNet docs. The customer network loses
connectivity several times every minute.
When watching the RG-1100 remotely, we never see a single radio
interface problem. Connectivity is solid and consistent, with low
two-digit ping times. But when pinging the Ethernet interface of the
RG-1100 from inside the customer network, ping times are always
mid-three-digits and the interface seems to just disappear for several
seconds three or four times every minute.
I have to wonder if the NAT processes are simply swamping the
(admittedly limited) resources of the RG-1100s; we have *never* seen
this problem on our routed, no-NAT network in the other city, but we
see it with *every* NAT installation. Or, maybe we're setting them up
incorrectly -- the docs are pretty sparse. Or, maybe there is a
problem with this version of the KarlBridge/Router software. One way
or another, we have a MAJOR problem that we need to solve... soon!
Any help would certainly be appreciated.
What we are running:
RG-1100 with card firmware v7.52
SR-4200 v4.02
Thanks,
-Brian
