Re: Cannot connect to Internet..

global (outside) 1 interface

You have an ip address where it says "interface" which is different than the outside interface address?

route outside 1

.193 is your gateway?

Are other services working? (like ping)

You incidentally might consider changing your snmp community string to something other than "public."

You could also turn some logging on to see what is happening....


Re: Cannot connect to Internet..

Hi Paul,

Your config looks OK, What is the error message your seeing when trying to browse the internet? Do you have LAN router with the PIX in the middle and a internet router in front, i.e. LAN-ROUTER-PIX-ROUTER-INTERNET. Also, try command 'clear xlate' and try again.

Thanks - Jay


Re: Cannot connect to Internet..

Hi Paul,

Different things can be wrong, although your config looks okay. Some questions could help isolating your problem.

1) can you ping your router (.193) from the PIX itself?

2) can you ping cisco site ( from the PIX

3) try opening with your browser

If all this works, there your config is okay.

Pinging from the inside will only work if you create an access-list on the outside interface for the response traffic! (have to remember that ICMP is not statefull inspected)

If all this works it could be the case that only name-resolving is not working, this is easy tyo determine by browsing to (if this works not, but it works with the IP-address, you're having problems with name resolving

Hope this helps. Please keep us posted on how things are going.

Kind regards,


If all this works you most likely have a problem
