Hi,
   I have setup a bridge between wirless LAN and Wired LAN as shown below


                          (Bridge Br0 on Linux box)
                            ____________________
                     |                          |
station....air if....wlan0---HostAP---eth0---wiredLAN---Proxy---internet
                           |____________________|

I am not able to browse the internet from the station.  I used ethereal on
the HostAP linux box (which is also acting as bridge )
to monitor the http request, I noticed that http request reaches the
internet Proxy server. But the station is not able to receive any packets
from the internet proxy.

Note: I used bride-utils by Lennert Buytenhenk to setup the bridge in the
linux box , I am using Prism2 HostAP driver.
Route table is as follows
Destination     Gateway         Genmask         Flags Metric Ref    Use
Iface
217.1.128.0     *                255.255.255.0   U     0      0       0 br0
loopback        *                255.0.0.0       U     0      0       0 lo
default         gateway.irc.com  0.0.0.0         UG    0      0       0 br0

Can any one please explain why I am NOT able to browse the internet? The
browser used to display "Connected to www.google.com  ..." and thats it. No
further response at all.

After a lot of struggle, I figured out that if I set the MTU size (Maximum
Transmission Unit) to anything less than 1400 bytes in the Station, I was
able to browse the internet.

What could be the problem!, why is that I have to change the MTU size to
make it work.

Thanks in advance,

Manjunathan Padua Y
