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

mail::dkim::dns5.18
Mail::DKIM::DNS(3) User Contributed Perl Documentation Mail::DKIM::DNS(3)
NAME
Mail::DKIM::DNS - performs DNS queries for Mail::DKIM
DESCRIPTION
This is the module that performs DNS queries for Mail::DKIM.
CONFIGURATION
This module has a couple configuration settings that the caller may want to use to customize the behavior of this module.
$Mail::DKIM::DNS::TIMEOUT
This global variable specifies the maximum amount of time (in seconds) to wait for a single DNS query to complete. The default is 10.
Mail::DKIM::DNS::resolver()
Use this global subroutine to get or replace the instance of Net::DNS::Resolver that Mail::DKIM uses. If set to undef (the default), then a
brand new default instance of Net::DNS::Resolver will be created the first time a DNS query is needed.
You will call this subroutine if you want to specify non-default options to Net::DNS::Resolver, such as different timeouts, or to enable
use of a persistent socket. For example:
# first, construct a custom DNS resolver
my $res = Net::DNS::Resolver->new(
udp_timeout => 3, tcp_timeout => 3, retry => 2,
);
$res->udppacketsize(1240);
$res->persistent_udp(1);
# then, tell Mail::DKIM to use this resolver
Mail::DKIM::DNS::resolver($res);
Mail::DKIM::DNS::enable_EDNS0()
This is a convenience subroutine that will construct an appropriate DNS resolver that uses EDNS0 (Extension mechanisms for DNS) to support
large DNS replies, and configure Mail::DKIM to use it. (As such, it should NOT be used in conjunction with the resolver() subroutine
described above.)
Mail::DKIM::DNS::enable_EDNS0();
Use of EDNS0 is recommended, since it reduces the need for falling back to TCP when dealing with large DNS packets. However, it is not
enabled by default because some Internet firewalls which do deep inspection of packets are not able to process EDNS0-enabled packets. When
there is a firewall on a path to a DNS resolver, the EDNS0 feature should be specifically tested before enabling.
