Has anyone experience or recommendations for a dual-WAN router?  I've read
some pretty horrendous reviews on Netgear and Edimax.  Not seen anything
either good or bad on Draytek Vigor.  My needs are pretty basic - want to
run a couple of simple servers unattended with fail-over between two WAN
access lines.  Load balancing would be nice but fail-over is primary need.

If the WANs have dynamically assigned addresses and if both are working
simultaneously, can such routers help remote clients to identify the IP
addresses of both WAN connection?
