One thing I noticed in the previous versions of the RV0xx series was only the RV082 could handle split dns over a vpn tunnel. From a post over on the cisco forums
, it appears the RV016 v3 cannot handle split DNS either, even though the manual indicates the device should be able to. Can you please confirm if split dns is a working feature on VPN tunnels for the RV042 v3?
Also, in the previous versions of the RV0xx series, it's actually impossible to block DNS queries from the LAN to the WAN, if say you were filtering the internet using DNS (opendns, dyndns internet guide, et all). Interesting little gotchya.
