Dear experts, I asked a question some weeks ago regarding sharing bandwidth among several WAN interfaces. Tom answered that my problem was because of having an "ancient" version of Ubuntu. Now the latest Ubuntu 8.04 LTS has come out, and I have been attempting to upgrade, but have run into an apparent bug that prevents the LAN from receiving internet through the PPPoE lines. While that is an Ubuntu bug, apparently, and no concern of this list, I've run into some online advice that brings me to some questions regarding shorewall. The advice I found said to clear the iptables with such commands as these:
sudo iptables -F sudo iptables -X sudo iptables -P INPUT ACCEPT sudo iptables -P OUTPUT ACCEPT The instructions were that this would completely open up the iptables, and would require a firewall to take care of the security in place of the iptables. But now I ask: 1) Is this safe? 2) Does shorewall replace ALL of the necessary iptables rules with its own secure policies, or does it merely adjust the tables already there? 3) Would there be any better way of opening up the iptables? If you're interested in the background issue with Ubuntu that I'm dealing with, and the advice I found online, you may look here: http://ubuntuforums.org/showthread.php?t=781744&highlight=linux+pppoe+ERROR+while+getting+interface+flags%26quot%3B+%26quot%3B70-persistent-net.rules Thank you! _________________________________________________________________ Get Free (PRODUCT) RED™ Emoticons, Winks and Display Pics. http://joinred.spaces.live.com?ocid=TXT_HMTG_prodredemoticons_052008 ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
