General Overview;

I have comcast dsl modem w/ boost connecting directly to my pix 501 with a crossover.
On eth0 i am not able to bring that port online. The message for some reason keeps showing "line protocol down-  see below.
I use a cross and a straight from the modem to the pix - dnw.
Also, i did the reboot thing but no dice - dnw

Any help with this is much appericated.
