I'm trying to get the "Range (DMZ & WAN within same subnet)" feature working with RV042v3 (4.2.2.08). The RV042 works as a firewall router, and is placed behind an old RV016 acting as a Internet and VPN gateway. As the old RV0xx are unable to filter the traffic arriving through IPSec VPN I placed a set in router mode RV042v3 in betwenn the VPN gateway and LAN. The problem is to use the same RV042v3 device as a firewall for WiFi traffic with the DMZ feature. Right now a WRT54G v7 is the WiFi access point and is placed behind RV016 in a separate subnet. But, when I move the WRT54G to the DMZ port of the RV042v3 I can no longer ping it from the LAN. I had no problems with making use of the DMZ range mode feature in the RV082v1. But the same function in RV042v3 does seem to work quite differently and I can not make it work, for some reason.
