there is something weird going on with my firewall.
I've got several servers set up to the public internet and from time to time (pretty much regularly) I'm not able to reach any of them. I also set up the firewall to be as safe as possible.
Now the mysterious part is: as soon as I make any trivial change to the settings and immediately revert it (so that changes are written to the config file) I can reach my server again.
So, I end up changing the position (or anything else) of my rules, change it back, safe again: I'm back up.
What the hell is this?? I'm really getting tired of doing this.
