If your PC can not ping the PIX, then you may have a ACL not allowing.

Can you ping from PIX to your PC?

from PIX to Internet?

These could be ACLs you are missing.

i allowed the PC to ping to PIX but only the inside interface didn't response, when i reboot the pix it start responding. i didn't understand the problem why pix behave like this,

please help and thanks for response.

The PIX can be a good device to use but sometimes it does too much good. If you don't put a command to allow echo-replies, when you ping the pix it will not respond to you. Mind you, you could be hitting it, but without the proper commands on the PIX, it will not respond back. Same goes for traffic, if you don't allow traffic to the outside, it will not let you get out. I hope this makes sense.

Thanks and let me know if it doesn't.
