[OLSR-users] Problems to transmit two hops away...

Hi there...

I set up a testbed with four computers using OLSRD and it was working
properly... but now (after two weeks of not using it) I cannot do a ping
to reach a computer located more than one hop away...

I though that the the forwarding node could have the FORWARDING attribute
blocked, but I checked the IPTables and it is not like that... the output
of "iptables --list" at the forwarding computer is:


Chain INPUT (policy ACCEPT)
target     prot opt source               destination
DROP       all  --  192.168.11.4         anywhere
ACCEPT     udp  --  anywhere             anywhere            udp dpt:698

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination
ACCEPT     all  --  anywhere             anywhere

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination
ACCEPT     all  --  anywhere             anywhere


I am trying to PING from 192.168.11.3 to 192.168.11.1 passing by
192.168.11.2, but I get the following output..

PING 192.168.11.1 (192.168.11.1) 56(84) bytes of data.

The routing table of the transmitter computer (192.168.11.3) is:

I have tried every idea that has came to my mind but I cannot make it
work... Any idea anybody?


Thanks in advance
