Hello, I can't get any traffic out through my PIX.  From the pix cli I can ping out to internet sites, I just can't get anything translated through.  The inside interface is working as well because I can pdm to it.   Below is my config.  Please help?  Thanks - Jim

With what you have, you can't ping anything outside the pix, but you should be able to browse the Internet.
Make sure you have your default gateway set to the PIX inside, and your DNS nameserver set to either your local DNS server with root hints, or a public dns server. Unlike many soho firewall/routers, the PIX will not proxy dns and you cannot use its IP address as your nameserver.

If you want to ping something, then you need to create an access-list and apply it
 access-list icmp permit icmp any any
 access-group icmp in interface outside

Thanks for the reply.  I didn't try to ping through the pix.  I checked all these things before I posted:  I do have the dg as and the dns is an external dns server.  I tried telnetting to a known telnet IP and also to an external mail server on port 25.  I also tried to get to google but still no luck. .  Immediately after I tried that I did a show xlate command and it returned 0.
  I was hoping I was just missing something obvious.  What do you think?  Thanks - Jim

your config is plain and simple. I had similar case before, my fix was reboot PC and reload PIX. I know this sound silly.

There is nothing missing in the PIX config. The 520 is old product and a reboot might just help. Be sure to save the config first...

I split the points between lrmoore and magicomminc.  lrmoore had great advice.  I had already done that but I didn't articulate it in my initial post.  I had done a "reload" of the pix but no help.  When I came in this morning powered down the pix then restarted and it all worked as planned??? So I gave 65 points to magicomminc.  Thank you both for your help!! - Jim
