NAT loopback is needed to accomplish this, and it is simple and safe. If you’re like me, you simply want internal and external access to operate in the same way. There are any number of valid reasons why you’d want to allow NAT loopback on your network. Internally, if NAT loopback is disabled or blocked, you would not be able to access this the same way. From an outside network, you could simply visit your external IP address from a browser to access the web server. For instance, say your router forwards port 80 to a web server on your LAN. The above procedure should rule out any effect that the Ooma device has on your Modem or Router, except a slight extra load.NAT loopback is what your router performs when you try to access your external IP address from within your LAN. When the Modem is done booting reboot your Router, when the Router is done booting, reboot your Ooma device. Click on Internet, go down to INTERNET Port MAC Address: and change setting from Automatic to Use Built In. Access your Ooma Setup pages by typing in your computer browser window. Temporarily turn off Wi-Fi in the computer, if turned on. If your connection is Modem-Router-Ooma, temporarily connect a network cable from your Ooma device home port, to the wired LAN port of a computer. To help stabilize your Ooma Internet connection turn off MAC address Spoofing by doing the following: But Ooma MAC address Spoofing might be causing this problem. This sound more like a Modem or Router problem, than an Ooma problem. Doesn't ooma understand that most people who use these services understand basic security requirements such as firewalls?Ġoma wrote:I have placed my ooma telo behind my linksys wrt54g (dd-wrt firewall - Firmware: DD-WRT v24-sp2 (10/10/09) vpn). I do not want to have ooma in front of my router and the DHCP/QoS settings that are built into it are pretty much useless. Ooma is set to request a static IP outside the router's range to prevent conflict, the rest of my network gets the ip from DHCP daemon running on the router.Ĭould this be ooma's built in DHCP responding to requests on another subnet mask? Have tried with proper QoS/port forwarding set on the dd-wrt router. This persists until I power cycle everything on my network (modem, router, ooma). I still can ping my router however just not outside addresses (e.g.

The problem is every once and a while my entire LAN stops being able to communicate with the outside network. I have placed my ooma telo behind my linksys wrt54g (dd-wrt firewall - Firmware: DD-WRT v24-sp2 (10/10/09) vpn).
