Hi John--
Sorry!! john that was my typo. Well i tried it again with all instructions.
I will provide complete summary of the errors that are coming to get a
better hint from your side.
Again i am testing it with two nodes. I CAN PING BACK AND FORTH WITH "JUST"
CLICK CONFIGURATION THRU THE WIRELESS INTERFACE(Wlan0)
Now i am trying to ping the eth0 interface on the GATEWAY NODE:
GATEWAY NODE:
Followed instructions on ur madwifi.stripped page and enabled it with:
1) ./conf/gen_config_roofnet.pl --dev "wlan0" --gateway 1 > /click/config
2) /sbin/iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
3) echo 1 > /proc/sys/net/ipv4/ip_forward ( IP FORWARDING ENABLED)

OTHER NODE:
1) ./conf/gen_config_roofnet.pl --dev "wlan0" --gateway 1 > /click/config
2) ifdown eth0
3) route command:

6) Command "route -n" :

0.0.0.0 0.0.0.0 0.0.0.0 UG 0 0 0
srcr
All Looks fine!! expect default gateway is missing( is this is the problem?)
Now i try to ping from OTHER NODE to eth0 interface of GATEWAY NODE.
ping 153.90.196.95( Ip ADDRESS OF eth0 of GATEWAY NODE)--- nothing!!
Do this "tcpdump -i srcr": To see if the packets are going out -- i See
packets going to OUR SERVERS, like 5.8.11.168 (IP address of srcr on OTHER
NODE) sends requests to 153.90.192.10, 153.90.2.15(which are our DNS
servers).
I do "tcpdump -i srcr" on the GATEWAY node: Wait for a long time!! NOTHING
IS COMING!!, it should i think if it is sending packets thru this interface
of GATEWAY NODE.
Now i do "dmesg" on OTHER NODE to see if kernel giving some messages:
This is what i see:
chatter: SRCR srcr : got invalid dst 0.0.0.0
ON THE WHOLE SCREEN
I Do : more /click/srcr_gw/gateway_stats --NOTHING!!
--------------------------------------------------------------
I also set the IP address of "srcr" of the GATEWAY node as the "default
gateway" on the OTHER NODE(JUST TRYING!!)--Nothing again
command: route add default gw 5.35.253.45 srcr ( THIS COMMAND WAS EXECUTED
AT OTHER NODE)
command:"route -n" after this:ON OTHER NODE
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use
Iface
5.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 srcr
6.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0
wlan0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 5.35.253.45 0.0.0.0 UG 0 0 0
srcr
Again tcpdump -i srcr, see this:
#arp who-has 5.35.253.45(IP Address of SRCR interface on GATEWAY NODE) tell
5.8.11.168 (Ip address of srcr on OTHER NODE)
#arp reply 5.35.253.45 is-at 1:1:1:1:1:1 ( it seems like some kind of bogus
hw address is assigned)
I am not sure what to do now!! Do i need to set "default gateway" on the
default route of other node. If yes !! shall i set it as : 5.35.253.254.
-----------------------------------------------------------------
I hope you can able to provide some hint with this information. I hope you
will reply soon!!
Thanx
