DNS won't resolver through router/proxy

[niknight]

I have RedHat8 running on a small LAN. My proxy/router has DNS and NAT enabled and is working fine. I can ping internet addresses by IP, but not by name. I have at times managed to get the RH8 box to use the proxy's DNS for name resolving but it is lost after reboot.
Here's the setup:

Router/proxy server:
IP: 10.0.0.1
Subnet: 255.255.255.0

RH8 box:
IP: 10.0.0.140
subnet: 255.255.255.0

Contents of /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
USERCTL=yes
PEERDNS=yes
TYPE=Ethernet
IPADDR=10.0.0.140
NETMASK=255.255.255.0
GATEWAY=10.0.0.1
NETWORK=10.0.0.0
BROADCAST=10.0.0.255

Contents of /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=localhost.localdomain
GATEWAY=10.0.0.1

Contents of /etc/resolv.conf
; generated by /sbin/dhclient-script
search 10.0.0.1
nameserver 10.0.0.1

Contents of /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.

127.0.0.1 localhost.localdomain localhost
10.0.0.140 mypc mypc.localdomain
10.0.0.1 ntbox ntbox.localdomain

Any ideas anybody. This is slowly killing me. Aarrrghhh!

You need to specify your ISPs DNS server in /etc/resolv.conf.

nameserver dns1
nameserver dns2

etc. It will enable your RH box to resolve names. Then you can install DNS server for your internal network. Install 'bind' package, then 'caching-nameserver'. Change dns for your nt box to rh box. And if it won't work, let us know.

Yup, I've done that now. What really had me confused is that on a few occasions, the NT box WAS resolving domain names and it still does for the Win98SE box on my LAN.

Still, it's working perfectly now, so I guess I'll leave well enough alone.

Thanks anyway.
