[OLSR-users] problem about olsrd-0.4.9

[ken chung]

I run olsrd between two machines both are Linux

One of them seem cannot receive any olsr packet generated by other.

I think that these packets are filtered by iptables.

but what command I should enter to accept all packet from port 698?
I already enter " iptables -A INPUT -p udp --dport 698 -j ACCEPT"

but the node still cannot receive olsr packet

Can anyone help me?
