*** Before anyone steps in as says I should have suggested bridge mode, well that's a better idea than using DMZ but if you've got both a Telmex Internet line and phone from them too, then going bridge will disable your internal ATA (VOIP logic). The VOIP login credentials will not be given to you by Telmex and it's unlikely you could configure a stand-alone ATA like a Linksys SPA-2102 to work with their SIP system even if you had all the config data. I've read there are also serial number pass backs to their equipment and you can't really get another ATA talking to their VOIP network. So for that reason the DMZ option is basically your main way of still allowing open ports into your network while configuring those on your new router, and that's if you have phone service along with your Internet. Stand alone and with no Telmex land-line (fiber-line LOL) you can give bridge mode a try which disables all the Telmex router except for the modem part and your router then is open to handle external connect attempts as you have adjusted your firewall.
