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

protocols
protocols(4) File Formats protocols(4)
NAME
protocols - protocol name database
SYNOPSIS
/etc/inet/protocols
/etc/protocols
DESCRIPTION
The protocols file is a local source of information regarding the known protocols used in the DARPA Internet. The protocols file can be
used in conjunction with or instead of other protocols sources, including the NIS maps ``protcols.byname'' and "protocols.bynumber" and the
NIS+ table ``protocols''. Programs use the getprotobyname(3SOCKET) routine to access this information.
The protocols file has one line for each protocol. The line has the following format:
official-protocol-name protocol-number aliases
Items are separated by any number of blanks and/or <TAB> characters. A `#' indicates the beginning of a comment; characters up to the end
of the line are not interpreted by routines which search the file. Protocol names may contain any printable character other than a field
delimiter, <NEWLINE>, or comment character.
EXAMPLES
Example 1: A Sample Database
The following is a sample database:
#
# Internet (IP) protocols
#
ip 0 IP # internet protocol, pseudo protocol number
icmp 1 ICMP # internet control message protocol
ggp 3 GGP # gateway-gateway protocol
tcp 6 TCP # transmission control protocol
egp 8 EGP # exterior gateway protocol
pup 12 PUP # PARC universal packet protocol
udp 17 UDP # user datagram protocol
#
# Internet (IPv6) extension headers
#
hopopt 0 HOPOPT # Hop-by-hop options for IPv6
ipv6 41 IPv6 # IPv6 in IP encapsulation
ipv6-route 43 IPv6-Route # Routing header for IPv6
ipv6-frag 44 IPv6-Frag # Fragment header for IPv6
esp 50 ESP # Encap Security Payload for IPv6
ah 51 AH # Authentication Header for IPv6
ipv6-icmp 58 IPv6-ICMP # IPv6 internet control message protocol
ipv6-nonxt 59 IPv6-NoNxt # No next header extension header for IPv6
ipv6-opts 60 IPv6-Opts # Destination Options for IPv6
FILES
/etc/nsswitch.conf configuration file for name-service switch
SEE ALSO
getprotobyname(3SOCKET), nsswitch.conf(4)
NOTES
/etc/inet/protocols is the official SVR4 name of the protocols file. The symbolic link /etc/protocols exists for BSD compatibility.
