PIX 501

I have a PIX that I thought ws successfully setup, but apparently not. I can ping outside resources from within the PIX by IP address only, I cannot ping by DNS name(maybe by design?). However, the server attached to the switch from the PIX cannot get beyond the PIX. The server CAN ping the private address assigned to the PIX and vise-versa, but no outside traffice. Below is my configuration. Any help would be appreciated.

Re: PIX 501

For basic inside to outside connections without yet configuring for outside to in access. eg. All out, none in.


nat (inside) 0 access-list inside_access_in

access-list inside_access_in permit ip any


global (outside) 1 *ISP ASSIGNED 2nd IP*


global (outside) 1 interface


access-list 101 icmp any any

access-group 101 in interface outside

for testing ping. ICMP packets must be permitted back in. All other traffic by default is permitted inside to out.

clear xlate then check following link
