PIX 501 connected to a residential cable modem. Speedtests are giving me 3mbit down. When I plug a machine into the cable modem I am getting 10-12mbit.

Ensure that the speed and duplex negotioated for the outside are correct, issue a "show interface e0" and see if you have any input/output errors.

No error on the sh int command. I will remove those nat commands and see what happens.

No difference in speed with the NAT commands removed. :(
