    Hi, I am using a Linksys SPA2102 VOIP adatper plugged into port 2 on the LAN side of my WRV200, and everything works fine for a while, but then my VOIP connection drops (nothing else is affected). I power off and on the WRV200 and VOIP works again ... for a while. Repeat.

    I have forwarded UDP ports 5000-5999 and 16000-16500 to the SPA2102 (set to static IP) and also tried putting the SPA2102 in the DMZ with no effect.

    Am I missing something in my WRV200 configuration???

    Are you sure thats all you need to forward, i dont know that particular adapter but most voip needs port 10000 - ? (i forget the upper limit).

    I was having the same problem: linksys support tel me that i have to change ip of the lan : i was 192.9.250.x and i have to put a network like this: 192.168.y.x .
    After, the PAP2 work well !!! Why, i don't know but it is ok for me. My WRV is a 1.0.33.

    whois will tell you that IPv4 addresses - are assigned to Sun Microsystems. If you are not Sun Microsystems, it is asking for trouble to use 192.9.250.x. That being said, the only trouble that I would expect would be that you could not reach those Sun addresses on the internet from your LAN.

    Maybe whatever mechanism you are using to do NAT traversal objects to you hijacking globally routable IP addresses.

    If you wish to learn more, see RFC 1918 to find out about what addresses you ought to be using. Anything in 192.168.y.x is an example, but there are others. http://www.faqs.org/rfcs/rfc1918.html

    I had the same problem, but when I disabled SIP ALG in firewall, it works just fine !
    Here's my setup :

    I have enabled webmanagement on WAN port 80, to be able to configure the SPA2102 on my LAN, and setup LAN on SPA2102 in bridging instead of DHCP.
