Hi:

I'm using the SPA2102 for my VFX setup, and has the LAN side set to bridge mode as my ADSL modem/router is already donig NAT, and I don't want to do double-NAT on it. I've tried set it to bridge mode, and hit submit to save the changes, but I noticed every now and then (usually a couple of days) it will just revert back to NAT mode.

Is there a way to force the SPA2102 to remain in bridge mode permanently? Or does Xnet do a config load from time to time that will cause this behaviour?

Thanks.

I had a similar problem and gave up on Bridge Mode in the end. In my case, the IP address on the WAN side got forced to all zeroes even though I had different subnets for the WAN and LAN port.

So I have just ended up using it as an ATA, with the LAN port remaining unconnected and all has been working fine for over a year now.

Others here like Gordy7 have managed to get their SPA2102 working in Bridge Mode, but for me it isn't worth the effort to go back and rearrange the LAN while I try again. We have a FS/FS connection, and the lack of QoS hasn't caused any issues so far. I have even sent faxes through the SPA2102 without any problem, and that's a pretty good test for any VoIP system.

Just a follow up on my bridge mode config for the SPA2102.

I too have found that in Bridge mode the WAN and LAN ports are 0.0.0.0
Someone in this forum said that my setup would be ok and the phone would work.

Pain though - because you can't get in to manage the router.
You have to reset the network to .0.x and reset the SPA2102 to see it on 192.168.0.1

However while I am waiting for WxC to get my phones going this is my new bridge config.

I now have my SPA in bridge mode with WAN management enabled.

The physical set up is as recommended for QoS:

Internet
ADSL Router with NAT
SPA Router in Bridge mode with WAN management.
Switch
All internal network stuff.

SPA2102 setup:

WAN Setup
Static IP
IP 192.168.1.8
GW 192.168.1.9
Mask 255.255.255.0
Remote management=YES

LAN setup
Network service Bridge (was NAT)
DHCP=No

ADSL router
192.168.1.9

Hope it all works :-)
Surfing the web is ok.
NAT is ok
Just waiting for the phones to work :-)

Cheers

My first ever AM radio network connection was with a 1MHz AM crystal(OA91) radio receiver.

I have similar setup, but it still switches back to NAt mode from time to time. I think it usually switches after an incoming call.

Anyone has any ideas?

Before you make this to bride mode note the following
WAN Setup
Connection Type: Static IP - Add your static IP
Enable WAN Web Server:Yes - this is important for you to access you SPA in Webbrowser
LAN Setup:
Then Make your SPA bridge mode.

When you make you SPA bridge mode you LAN ports become 0.0.0.0 your WAN acts like the LAN, this is why its called bridge mode, you are bridging WAN and LAN.
