Special Forums IP Networking Select DNS Servers depending on the domain Post 302315931 by shico1973 on Wednesday 13th of May 2009 02:26:47 PM

while you are VPN connected ; can you try to resolve anything using you local DNS ? ; can you even ping your local DNS ?
i have a feeling that your VPN connection should not filter out any communication with local IP network ? if so then test this criteria by trying to do a DNS query while VPN connected
some thing like
#nslookup
then set the server to your local server
>server my.dns.ip.address
then try to resolve any local DNS name

if the request times out this means that your resolver [DNS client] could not communicate with your DNS server ! ; if not then this means that you will need to add the local DNS to the list of valid DNS servers that is used while you are VPN connected [this is related with the configuration acquisition that is made upon VPN connection ]

regards

NAME
resolv.conf - Domain Name System resolver configuration SYNOPSIS
/etc/resolv.conf DESCRIPTION
The /etc/resolv.conf is used to configure how the host will use the Domain Name System to resolve hostnames to IP addresses. It may con- tain these two lines: nameserver IP-address domain domain-name The nameserver entry tells the IP address of the host to use for DNS queries. If it is set to 127.0.0.1 (which is the default) then the local name daemon is used that may use the /etc/hosts database to translate host names. You normally only need a nameserver entry if the name server is at the other side of a router. The default nonamed name server can't look beyond the local network. The domain entry tells the default domain to use for unqualified hostnames. This entry is usually not given in which case the domain of the local host is used. The long version of this story can be found in resolver(5). FILES
/etc/resolv.conf DNS resolver configuration file. SEE ALSO
