Hi,
my freifunk firmware is v1.6.29 and the batmand version is :B.A.T.M.A.N. 0.2 rv502 (compability version 3)
please consider upgrading to the latest code. 0.2 is outdated (released May 2007). Version 0.3 is the current stable whereas the 0.3.1 release will happen in the coming days.
I read the HowTO from Freifunk Leipzig about the configuration of BATMAN, look here http://wiki.leipzig.freifunk.net/BATMAN. How is the configuration If I want to run BATMAN in Ubuntu Intrepid? How can I configure the IPTABLES ?
Unless you run your own firewall settings I could imagine you wont need to configure iptables. The routers need these settings because they use iptables heavily (unlike a normal desktop).
