DNS Servers

[199002003]

I have two locations and Site A has the Domain setup, and SiteB is in workgroup, both of sites have Firewall enabled with site2 site vpn connected; am I going to reduce the traffic a lot if I am going to setup the DNS server at the work group(SiteB)? because now, I setup my siteB to use SiteA's DNS server.

TIA

You aren't going to reduce traffic a lot, since DNS traffic is light, with virtually no payload. If you could do a pie-chart of all the VPN traffic, you'd probably see DNS traffic take up 3% or less of the bandwidth.

The question should be more about redundancy than traffic. If your VPN gives you trouble or you lose your internet connection at the main site, you may not have any access to the internet from SiteB, unless you configure your ISP's DNS servers as secondary DNS servers.

I forgot to mention that I have T1 connection on both end, on both end firewalls were configured to use ISP's DNS as the primary DNS. and the Site A has its own DNS(internally) Will this matter?

It doesn't really matter what the firewalls are using for DNS as much as it matters what the clients in site B are using. Just add one of the ISP DNS servers as the second DNS server on the siteB clients to make sure they can still get on the internet if your cross-site connection goes down for some reason.
