PIX 501 not receiving DHCP on external interface (default config)

I'm having problems with configuring a PIX to pick up a dhcp ip address on its external interface, and allow pings from the PIX to

the external world.

I have just reset the PIX and set back to factory defaults: write erase Reload configure factory-default write mem

(1) Its not picking up dhcp IP from my adsl router: pixfirewall# show ip address outside dhcp Temp IP addr: 0.0.0.0 for peer on Interface: outside Temp sub net mask: 0.0.0.0 DHCP Lease server: 0.0.0.0, state: 1 Selecting DHCP transaction id: 0x1B8898 Lease: 0 secs, Renewal: 0 secs, Rebind: 0 secs Next timer fires after: 1 seconds Retry count: 1 Client-ID: cisco-0016.c7f9.c402-outside

Is there a way to reattempt to receive a dhcp address?

(2) Also. If I set a static external IP address, the PIX501 cannot ping my ADSL router. pixfirewall# ping 192.168.1.254 192.168.1.254 NO response received -- 1000ms 192.168.1.254 NO response received -- 1000ms 192.168.1.254 NO response received -- 1000ms

Thanks Nick

Can you post the result of a

sh interface

You may have cabling problems. Do you have a cross-over cable between your PIX and router ?

What is your static external IP? Is 192.168.1.254 is ADSl Router IP?

Use the PIX capture command to see if the PIX is transmitting DHCP requests and to see if it is receiving DHCP response.

Depending on twhat you see or do not see in the capture traces, you should have an idea where to look next

I replaced the external cable, and suddenly I received a dhcp address, and could ping the router and the outside world.

Thank you all for your ideas. Nick
