Losing bandwidth using Cisco PIX 501c from the cable modem to the PIX
We have cable internet service that is supposed to provide us with 10.0 mbps. When I connect a computer directly to the cable modem the test show a bandwidth of 10.1 mbps. I then connect the cable modem to the PIX and connect my computer to the PIX and the bandwith tests at 7.6mbps. Is this normal? If not is there something in the configuration for the PIX (below)that is affecting the bandwidth? Or is this modek of PIX the cause, and if so what can you recommend?

It is already confifgured as you indicate??
ASKER
If this is half duplex are you suggesting to configure it as full duplex and how so?
ASKER
Should these lines read:
interface ethernet0 100full
interface ethernet1 100full
interface ethernet0 100full
interface ethernet1 100full
Your inside is half duplex. Make it full duplex.
#config term
(config)#interf ethernet0 10full
(config)#exit
#write mem
easy cheesy

ASKER
Great - should I make it 100 rather than 10?
Ethernet is not 100. That is fastethernet. So 'no'.
ASKER
I get the error message that
"ethernet0 interface can only be set to 10baset"
"ethernet0 interface can only be set to 10baset"

Any suggestions as to what will accomplish what we have defined in this PIX only doing that full duplex?
What?
The PIX is only capable of half duplex. The half duplex is causing the reduction in bandwidth. Full duplex support is a hardware issue not a configuration issue.

If this PIX cannot handle full duplex should I look for another model (used) that can handle full duplex and will use the same configuration code. If so which models would you suggest? Or is there a better new/inexpensive way to handle the 2 static ip addresses and all this config/hardware handles?
Your best bet would be a new ASA5505. It is far and away the best on the market to replace the PIX501.
Else if you can find a used 506e or 515e that would be a good alternative.
