[44net] Problems with iptables and ampr-ripd

Hi All, I am working on creating a gateway using the example at http://wiki.ampr.org/wiki/Ubuntu_Linux_Gateway_Example however I am running into a few problems. !. When I try to input the iptables command|| |"sudo iptables -A OUTPUT -i lo -j ACCEPT"| ||under the protecting the gateway section, i get this error: "iptables v1.6.0: Can't use -i with OUTPUT Try `iptables -h' or 'iptables --help' for more information." 2. after seemingly successfully making and installing ampr-ripd 2.3, when I try to run "sudo ./find_pass.sh" It gives me the standard "sudo: ./find_pass.sh: command not found" and I cant figure out what to do. Further when I try to run the "./ampr-ripd -d -v -i ampr0" line from within the shell script, I get "-bash: ./ampr-ripd: No such file or directory" Help with either problem would be appreciated. 73, Augustine W8AWT || ||
