dig & nslookup resolve, ping fails to resolve -- ???

I'm running SuSE 8.0 on a 3 NIC firewall/router system.

I have /etc/resolv.conf set to use a system in the DMZ as the nameserver, and dig and nslookup work fine with that.  If I try to ping someone, though, I get unknown host.

If I put my ISPs nameservers in /etc/resolv.conf, ping works fine too.

maybe you setup VIEWS in your DNS. if you do not allow ip's from inside, or if you are masquerading or SNATing something, just take in account which ip's are the ones you must answer to in the DNS.

check what interface(s) are you using when you try to ping (I suspect this is a firewall problem). You can change the interafce with ping -I <interface>
