That's correct. But, your proposed configuration wouldn't solve this problem - if the firewall fails, the Nagios servers can't contact each other anyway, so they could never agree on what's up and what's down. > I made a slight error in my original description - when the firewall "goes > down" it cant contact anything at both locations, not just Site A, due to > the fact that the protected interface stays up but just denies all > traffic. > > We are currently working on this with GTA but im losing the will to live > with 300 texts virtually every night!! I've dealt with this situation before, and I've ended up implementing two mostly standalone Nagios systems. They each check their own site, so if their external network goes away they are still able to monitor and alert for the things they're responsible for (you have to use out-of-band notifications of course). They also each check each other's *site*, ala the other site's firewall, so the Nagios server at site A can alert and let you know if site B goes away, but it *doesn't* try to alert you for all of the hosts and services at site B. -- "The problem with quotes on the internet is that it's very hard to verify their authenticity." -- Abraham Lincoln ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
