Divert DNS traffic to another gateway
hello all,
i have a local bind9 dns server running on debian.
its default gateway is 10.0.0.x. This internet gateway
has limited bandwidth.
we have another high speed internet connection(adsl) and the gateway to access this connection is 10.0.0.y.
all users in the office are using 10.0.0.x as dns server(its distibuted by the dhcp server)
i want my bind dns server to use the adsl (10.0.0.y) connection to do lookups on external dns servers(e.g the isp dns server or google public dns server) instead of the 10.0.0.x gateway.
please help and advise, how can i solve out this issue.
thanks
coolatt

desproxy-dns
desproxy-dns(1) User Commands desproxy-dns(1)
NAME
desproxy-dns - DNS for dynamic connections
SYNOPSIS
desproxy-dns dns_server proxy_host proxy_port
OPTIONS
None
DESCRIPTION
If you have direct DNS access then you don't need to do anything else. You know you have direct DNS access if you can resolve host names
to IP addresses.
NOTE: as desproxy-dns listens in port 53 (which is less than 1024) you may need administrator privileges to exec desproxy-dns (in fact if
you are running UN*X, you actually have to run desproxy-dns as root).
OK, so you have a dns server accessible now. But your computer doesn't know anything about that. You must configure your network
accordingly (again, need to be root in UN*X).
Edit /etc/resolv.conf and add the line "nameserver 127.0.0.1". You don't have to restart anything. Just test ping and see if it works.
ENVIRONMENT
None.
FILES
None.
