    first post, fairly new to the pix so if I'm an idiot, don't hesitate to tell me so.

    I have a pretty simple network, cable modem with static ip to pix to inside network.

    I have configured the pix to forward https, smtp rdp, and 3101 for BES, and it was working for several days, then suddenly stopped working.

    so I blew away the config and started over from scratch. it seemed to be working last night, then I get a call this morning that it isn't working.

    here's the config.

    I have rebooted the pix, replaced cables, it routes internet traffic fine, so I am fairly confident that it isn't a cabling issue. I did some troubleshooting with the isp, it is a business line so there are no ports being blocked. and when connected directly to the cable modem, I can access the ports remotely. so, I am very confused, as I said earlier, it seemed to be working last night, I tested it from http://www.mtgsy.net/dns/utilities.php and ran the port tester against it, as well as the ping test and it passed them all. any help would be greatly appreciated.
