So, in a nutshell, I have a cable modem getting my outside IP -> to the Telo, which is handing off a static IP to my router -> which is handing off a static IP to my laptop. My router is in the Telo's DMZ and ports are forwarded, but not showing as open from the Internet, to my laptop's IP. Any ideas why this wouldn't be working, especially when it was for a while? Thanks.
You need to blank the DMZ field in the Telo and double check on the rules for ports forwarding in the Advanced page of the telo setup page.
Hope this help, and please post back.
Are there better or worse practices in terms of how to setup the Telo and router and which port(s) to use? Here are some various combinations of techniques I think I've tried. In all cases, my router has the same port forwarding rules to my laptop's static IP address:
1) Telo first and last and DMZ all set to the same IP, outside of the usual DHCP range (which I've forgotten, but I think it starts at 172.27.35.10 and goes to .100 or .150). I've regularly tried one above the home port IP, that is 172.27.35.2. Router set to DHCP.
2) Same as above, but router set to static IP, with the WAN address the same as the address in the Telo's DMZ and first/last DHCP settings (all three the same, in my case 172.27.35.2), 255.255.255.0 subnet mask, and the home port's 172.27.35.1 for both default gateway and first static DNS.
3) Put Telo back to default DHCP settings and use the static router settings above to force the router to pick up a single address.
4) a) Have my router address in the Telo's DMZ *AND* have ports forwarded in the Telo to the same address (the one my router's using), b) use only the DMZ setting, or c) use only the port forwarding settings.
5) After making changes in setup.ooma.com a) reset the Telo by unplugging for 30 seconds and then letting it boot up again or b) don't bother, just save settings in setup.ooma.com.
6) [I haven't tried this lately] Use a static IP within the Telo's normal DCHP range, ie above 172.27.35.10. And does it matter - if you leave DHCP range settings on the Telo at their defaults - whether the IP you assign to your router is within or outside of this range?
7) Should I be rebooting my cable modem in the midst of all of this nonsense? My connection is fine, but I've had the same IP lease for several days, and maybe that's an issue?
Sorry, this is getting awfully confusing, but I just keep piling one thing on another and figure I'll never resolve the problem. Someone did write somewhere in the forums that it isn't a good idea to have you router in the Telo's DMZ and forward ports in the Telo to that same IP, but I don't know what the theory is behind that.
