WDS link problem: ping only

[michael schatz]

Hi-
I've established a WDS static link between two APs running hostAP (call
them AP:A and AP:B) under RedHat 9.0. AP:A and all wireless devices that
associate with it have full access to the internet (ping, DNS, web
browsing, ssh, etc). AP:B also has full access to the internet, but
all wireless devices associated with AP:B can only ping (only by using IP
addresses)....nothing else works( no DNS, no ssh, no web
browsing, etc). below
i give the architecture and the scripts on both APs (/etc/rc.local)
that i use to set up the WDS link with ipforwarding and routing. could
someone suggest what i'm missing in configuring the forwarding/routing
of AP:B's devices?


Thanks!

Mike
