Nothing is impossible, but as Tom has told people so many times, Shorewall isn't 'running' (it just configures stuff and quits). I would be VERY surprised if the firewall config itself was causing problems, and even more surprised if it could wipe your config. I'd be more inclined to think along the lines of perhaps, limited resources, flood of <something> from internet, system unable to cope. For example, I had to replace my ADSL model as the old one couldn't cope with the ARP table when running BitTorrents - and I also had to tune my network tables (maxed them out) for the Linux networking for the same reason. Even then I can't see how that would alter your config unless you've managed to cause filesystem corruption. Perhaps if you posted some key details about your setup - what sort of hardware (eg there's a bit difference between a router appliance with 64M RAM and a bit of flash, and a PC with a GByte of RAM and hard disk). ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
