ASA 5505 cannot ping Internet hosts by name ?

I can ping by IP address but not by name. I also cannot surf the web since name resolution does not work. My client's default gateway and DNS setting points to 10.1.1.1, which is the inside interface of the ASA.

The asa5500 series cannot act as DNS servers. You need to point your clients to a different DNS server - like 4.2.2.4 or something.

Guys, sorry I didn't explain it better, I'm not trying to make the ASA act as DNS, just trying to get it to pass through the DNS info from my ISP. What baffles me is that I had the entry checked in ASDM to enable DHCP auto configuration from interface outside, but that didn't seem to work? For some reason the ASA refuses to pass my BellSouth DNS server info to internal DHCP clients. My D-Link did this without an issue. Anyway, adding dhcpd dns x.x.x.x worked! I can't tell you how many hours I've spent troubleshooting this. Cheers!
