How to configure DNS server?

[sillyVM]

My setup is outside interface using DHCP (comcast), so it will have a DNS server on the outside. But when my client connects, the DNS server will automatically point to the my PIX. My question is, how do I let my client to automatically connect to the external DNS server or how can I make my pix as cached DNS server.

Much Thanks

MIne looks like this:

pix1(config)# sh dhcpd
dhcpd address 192.168.0.10-192.168.0.20 inside
dhcpd lease 3600
dhcpd ping_timeout 750
dhcpd auto_config outside
**auto_config dns 68.87.64.146 68.87.75.194
**auto_config domain hsd1.pa.comcast.net.
dhcpd enable inside

The PIX won't act as a DNS server. If your PIX is the DHCP server & client then

dhcpd auto_config outside
or statically via
dhcpd dns [DNS_Server_IP_#1] [DNS_Server_IP_#2]

I use 4.2.2.2 and 4.3.3.3. These are free DNS servers that anyone can use.

Thanks both of you, Supergrrover's answer is the one I am looking for. I am currently configured as a static dns looking up to my provider's dns server. I need the auto_config outside command. Thank you very much.

Kudos to both of u2.
