I want to change the internal interface speed. For some reason my download speed has decreased to 70 Kbps. I have reset the pix a few times and reset the modem, the switch is new. I want to change the duplex speed on my internal interface. but it says..
ethernet1 can only be set to 10baseT, 10full or auto.

>PIX Version 6.2(2)
PIX OS 6.3(3) will give you 100Mb full duplex capability

>interface ethernet0 10full
>interface ethernet1 10full

If your switchport connected to Ethernet1 is not also set to 10/full you will have problems. If your switch is not managable and you can't set the speed/duplex, then leave the PIX interfaces at "auto"

   interface ethernet1 auto

Eventually, you will have to convert your conduits to access-lists.

Correct. But you don't really need 100full because you're throttled at the other side to, what 2Mb?
The issue is that the switchport is set to autonegotiate, your PIX is set to 10full. Manually setting the duplex turns off the autonegotiation packet. If the switch does not receive an autonegotiation packet, it will most likely fall back to half-duplex. Now you have a duplex mismatch that is the culprit in your slowness..
From the PIX console, use "show interface" and look for collisions and error counts. If there are any errors, especially collisions, the problem will point to a duplex mismatch.

6.3(3) brought my 506 up to 100/full capability, but I'm only plugged into a 10Mb switch anyway.
