Yes, I have a static IP on the ADSL connection and it is setup for the same. Connects using MER and NAT is enabled. If I connect the router to DD-WRT's WAN port and change subnet of the ADSL private network (matching the same on WAN interface), then it works properly. -- Nilesh Govindarajan http://nileshgr.com
