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
220.127.116.11 * 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,
