Hello aLL. We have two internet access one ADSL connection and another 256Mbps internet dedicated link. We want to configure our firewall (iptables) to choose/detect and determine when one of that links goes down e automatically reasign another path to the internet. (like as a link backup). I know that I can do it writing a script, but I think its not beautiful... :) I tried to find something on the web but the documents was related to HA (high availability) which is not my case, I want to have just one firewall doing the job. Glad if you help! thanks Borda. --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com). Version: 6.0.481 / Virus Database: 277 - Release Date: 13/5/2003
