Hi,
My network was:
DSL Modem --- Pix501 --- internal
My Pix outside interface got the IP dynamically with the ip address outside dhcp setroute command. This worked fine.
I recently switched to Comcast because my DSL speed wasn't cutting it. So now my network looks like
Cable Modem (Motorola SB5120) ---- Pix501 --- internal.
However, my Pix is NOT getting an ip address. If I hook the cable modem directly up to my laptop, I pull a public IP from comcast just fine. However, it does not ever make it to the Pix.
Has anyone had any experience with this? Here is my Pix501 config:
