Can I add VOIP Gateway SPA2100-SU to the DMZ of Router BEFSR41 Ver 4 ?

Question

I am having multiple problems with dropped calls; need to reboot my LinkSys VOIP Gateway and so on, and my VOIP provider has suggested the following: "Add your Gateway (the physical device I guess) to the DMZ of your router." We are trying to tell the Router to give this VOIP Gateway, which gets its IP address via DHCP from the router, to essentially give this Gateway carte blanche to any port or destination it wants. I have NO idea how to do this on the BEFSR41, which is a CA model with Version 4 appended to its model number ? Can anyone send me how to advice ? - Mike BRYAN Ottawa Canada PM me for my email.

Answer 1

First thing is to assign a static IP on the WAN / Internet side of your SPA-2100 so that you can set that IP to the DMZ of the BEFSR41. If you are not sure how to assign a static IP address on the spa2100 or how to open the web interface of the spa2100 and befsr41, then you better refer to the KB articles from www.linksys.com/kb. Just type in something like spa2100 or befsr41.
By the way, you may also enable NAT mapping and NAT Keep alive in your spa2100 aside from opening / forwarding ports in the befsr41 (check out Answer ID 5242).  Lastly, enabling Send Resp To Src Port in the spa2100 is another option to try (this is under Voice > SIP > NAT Support Parameters).
It really requires much reading for us beginners to fully understand these devices. I am happy that I learned how to use the KBase site of Linksys since it gives me useful info about their products.
