Re: PIX-501 no internet access

Can you ping a public IP from the PIX? Can you ping your Internet gateway from the pix ( If not, make sure that your router and the outside interface of the PIX have the proper speed and duplex settings.


Re: PIX-501 no internet access


What error message do you get when you try to do nslookup from a inside PC? Also can you provide some syslog messages, do the following:

logging on

logging buffer debug

sh log

Can you post the above result.
