Hi, I have Tomato 1.28 installed on my router. I want to install asterisk on it. So I attach a thumb drive to it and mount it to /opt. I installed ipkg, then installed asterisk. It works fine for a while after each reboot. Then the thumb drive will get disconnected and reconnected by itself. The drive number changes from sda1, to sdb1, then to sdc1. It can't be kept to /opt even after I used uuid in the mounting command. Has anyone exeprienced the same problem? I enabled ftp, vpn service. Thanks.
