Thank you Craig for your input, I will change this on Monday and test it out.
So
subnet 10.154.19.0 netmask 255.255.255.254 {
should be changed to
==> subnet 10.154.19.0 netmask 255.255.255.0 {
range 10.154.19.10 10.154.19.20;
option domain-name-servers $DNS_SERVER_IP_ADDRESS_1, $DNS_SERVER_IP_ADDRESS_2;
option domain-name "$YOUR_DOMAIN_NAME";
option broadcast-address 10.154.19.31; to
option broadcast-address 10.154.19.255;
for $DNS_SERVER_IP_ADDRESS_1, $DNS_SERVER_IP_ADDRESS_2 should it I leave them
as is or do I put the ones that are on the host machine? or will it pick them
up automagically?
Do I need to have bind running as well?
Sorry to ask too many questions. Last time I was trying this, I tried webmin,
but I got confused with iptables and other little things. Will the iptables
part that I put in suffice also.
Thank you for your time and advice. When I get back to work on Monday, I will
try these suggestions and post back if I succeed or still have questions.
Regards,
Antonio
