After our (failover-less) Cisco firewall and main router was behaving increasingly flakey last Friday, it was up to poor old programmer me to come up with a quick replament. I commandeered an old HP server (the only thing with enough ports) and tried to get some kind of firewall/router distribution going. Easier said than done, as installing the base package seemed hard to impossible for most rivals (something with the RAID controller, I guess). So, thank you, ebox developers for that. I had to burn some midnight oil, but I finally was able to get a basic system going.
But now I'm running into some problems with one of the interfaces. I noticed several times that it basically lost all connections to other interfaces, yet within the subnet (i.e. switch) itself, everything was working ok. To me this would point either towards the gateway or the switch itself. I thought about something hogging the bandwidth, but it's either rather fast, or no connection at all...
I haven't seen anything relevant in the log files, so I wondered whether there's something I could turn on the main ebox interface, to have a more detailed interface/connection log. The dashboard graphs aren't really enough for a detailed analysis.
So I'd be happy for any suggestions to help me get rid of this ugly glitch.
