Re: Slow POP3 / SMTP / FTP connection from internal windoze machines to linux firewall (gateway)
Are you running any sort of internal DNS for the internal network? Also,
does each machine have it's own IP to the Internet or is it all behind a
proxy?

Re: Slow POP3 / SMTP / FTP connection from internal windoze machines to linux firewall (gateway)
Can you give us a detailed description of what your network looks like,
along with some network hardware descriptions?

Make it this:
options {
directory "/var/named";
forwarders { ISP backup 1 IP; ISP backup 2 IP; };
forward only;
listen-on { 10.0.0.1; };
};
> Or should it be for 10.0.0.1 instead of 127.0.0.1?
Nope. All DNS servers are masters for 127.0.0 since 127.0.0.1
always points to the local machine.

Brillant.

You'll need the /var/named/named.local file specified in named.conf .

Yah zone files for your internal static ips. A slave dns server as a backup
for the box you are working on. And most likely a change to your dhcp
server to tell all those Windows boxes where to get there DNS.

Hi...
Thanks for your reply. My questions on this are as follows:
1. The 2nd NIC's IP address is 10.0.0.1 for the internal machines. Would my
named.conf look like this:
options {
directory "/var/named";
};
;
zone "0.0.127.in-addr.arpa"{
type master;
file "named.local";
};
zone "." {
type hint;
file "";
};
Or should it be for 10.0.0.1 instead of 127.0.0.1?
2. The /etc/resolv.conf file should be as follows with my server as the
caching server?
search mydomain.com
nameserver 10.0.0.1
nameserver ISP backup 1 IP
nameserver ISP backup 2 IP
Is there anything else I need to setup?
