I've been using the Edimax BR-6524 dual WAN router for a while now.
It seems to basically work fine, however, I have not really tested out
its QOS or dual WAN features much yet.
One thing it does not seem to have is any easy way to say, "Heh
router, please send this particular request out over WAN 2,
not WAN 1." That can be important, because I've noticed some latency
sensitive applications (rdesktop, VNC) perform noticeably better over
DSL than cable modem.
The router does let you statically map particular LAN IP addresses to
different WAN interfaces. That's a pretty blunt instrument, but I
know it's possible to assign multiple IP addresses to a single
ethernet interface in Linux. So, maybe I can do that, then somehow
control which IP address gets used on the Linux box, whenever I invoke
wget or the like.
A few other fancy features of this router that I've noticed:
- It works as an NTP client, but unfortunately you can only give it
one NTP server to talk to, and you must enter the IP address of the
server, not a host name.
- It is set up to dynamic DNS with either dyndns.org or tzo.com, but
I haven't tried that.
- A stateful packet inspection firewall feature, which I also
haven't tried.
Unfortunately, AFAICT you can't telnet or ssh to this router, the only
way to configure it is via its web UI. No SSL on the web UI, just
plain http. Also, you can't even see the router status page unless
you first type in the admin password, which is foolish and annoying.
