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

NAME

SYNOPSIS
/etc/protocols
DESCRIPTION
The /etc/protocols file contains information about the known protocols used in the DARPA (Defense Advanced Research Projects Agency) Inter-
net. Each protocol is represented by a single line in the protocols file. Each entry is of the form: Name Number Aliases
The fields contain the following information: Official Internet protocol name. Protocol number. Unofficial names used for the protocol.
Items on a line are separated by one or more spaces or tab characters. Comments begin with the # (number sign), and routines that search
the protocols file do not interpret characters from the beginning of a comment to the end of the line. A protocol name can contain any
printable character except a field delimiter, newline character, or comment character.
The lines in the file appear as follows: # # Internet (IP) protocols # ip 0 IP # internet protocol, pseudo protocol number
