I'm trying to integrate a PIX 501 behind a Roadrunner cable modem.
I'm not able to ping the default gateway address that I receive from Time-Warner's DHCP server. (I have link lights on both the PIX and the cable modem, and in fact, do receive IP configuration from Time-Warner.) Most unusually, I get different IP addresses depending if I connect a PC or the PIX, completely different subnets.
I CAN ping the PC when it is directly connect to the cable modem.
Is there some issue peculiar to the Roadrunner? Any insight would be greatly appreciated.
