Thanks for the information.
But still there are some probles in the HNA settings and internet
connectivity.
I tried bu running the suggested command iptables --- also but problem
is not resolved.
Now I changed all PCs to the same subnet and the configuration is as
follows -
PC-A(10.105.12.200)<----->eth0(10.105.12.201)-PC-B-eth1(10.105.12.28)<--
--> Internet
Observations:
Instead of internet connection I tried to ping sytrms to/from the
internet LAN.
I concluded these points -
1. from any PC which is in internet LAN I am able to ping both
interfaces of PC-B but not PC-A.
2. from PC-A I am able to ping both interfaces of PC-A but not any PC of
internet LAN.
Please reply for any help or command which I need to run to get the
complete path!
Actually We are planning to have 10 Nodes woth olsr demon and one node
will be declared as HNA and then other nodes will access the internet
through HNA node. SO first I am trying the scenerio with two PC and
internet then with all the 10 nodes.
Thanks in advances -
The olsr.conf and route -n output on both PC ar as as follows -
