Hello,
I have read 'the' book'-"DNS and BIND" O'Reilly, faq's, online help, the
archives, and still have a question....
Do I -need- named ?, is the config below ok (usable and correct?)? thank
you for your help!
I have a single box RedHat 6.2, Bind 8.2.2P5, ProFTPD, sendmail-8.10.1.
I am running my internal net at 192.168.1.1/24 (eth0) and my isdn
62.224.188.56/29 (eth1) uswest is doing my primary and secondary dns, have
forwarding (networks ) and masquerading (ipchains forward eth1) setup, my
isdn router is 62.224.188.62. My gateway is set to the router @ .62. All
clients are NT with an nt DHCP server, default routes on the nt boxes are
192.168.1.1 dns pointed to uswest name servers).
I think this is a fairly common setup but I have not seen any specific
examples for this, witout doing my own DSN or mutiple virtual servers, or 3
machines with a central hub, etc...
My configuration below does not seem to work, I turned off named and I can
route to the internet and my mail server is working correctly, but my DNS
lookups are down, I can not ping anything on the other side of the server
(MS1). I had this working before, routing to www.whatever.com from IE5 on
the workstations (except the mail until I turned off named then the mail is
fine but dns is down).
When I run named the logs show
