WAN vs LAN

[tritch]

I tried everything I could find and could not make a phone call. Kept getting busy signal, incoming or outgoing. I tried placing it before the router, after the router, in the bathroom, out in the rain, no difference. I cannot see it on the router.

Modem/GM(WAN/LAN)/Router/Switch
Modem/Router/GM(LAN)/Switch
Modem/Router/Switch/GM(LAN)

Rebooted all devices in every order I could think of and no result. I did notice that having this thing plugged in behind my router was causing me all kinds of assigned IP problems on my network. Could not define it and the only way to get everything back online was to remove the GM completely.

Then today, I plugged the cable into the GM(WAN) port, then into the switch and the damned thing started working. The router sees it, I can even assign a specific IP. I still cannot log into the unit though.

Can someone please explain?

Skyforum, it's never going to work by connecting your modem, router or switch to the LAN port of the HT502. You must connect the WAN port of the HT502 to the Internet in some way for it to work. The LAN port on the HT502 is typically used for router function only. There should have been some sort of instruction sheet included in the box you received. If there wasn't, then Voipo slipped up.

Modem/GM(WAN/LAN)/Router/Switch
This setup would have only worked if you connected like this: Modem-> HT502 (WAN) -> HT502 (LAN) -> Router -> Switch
If your modem is already in bridged mode, you would likely need to release your public IP in your router before attempting to connect it this way otherwise it may not work at first. The HT502 needs to pull a public IP if the modem is bridged. You incur double NAT in this scenario, so there's a possibility some devices behind your router might have Internet connectivity problems. No port forwarding needed since the ATA is ahead of your router.


Modem/Router/GM(LAN)/Switch
This setup won't work at all. You must connect it like this: Modem-> Router -> HT502 (WAN) -> HT502 (LAN) -> Switch
In this scenario, I would bridge the HT502 so that all devices connected to your switch don't incur another NAT. Port forwarding maybe needed depending on your router's firewall.

No double NAT going on, so that's good. Port forwarding maybe needed depending on your router's firewall.

In all cases, it's a good idea to make sure your modem is in bridged mode to aviod double/triple NAT in your network. Cable modems by default are already bridged, but DSL modems are normally not.

I still cannot log into the unit though.

You normally log into the ATA via the LAN port. So, you will have to connect a laptop or PC to this port and log in using the default IP address of the ATA. If you want to log in to the ATA via the WAN port, then this feature will have to be turned on in the ATA's web configuration first, then you can access it via the IP address that your router assigned to the ATA.
