New Viasat Wifi Gateway in Bridge Mode - Disables VOIP phone service?

  • In Progress
I just upgraded to the new Unlimited Gold plan which came with the new (triangular) ViaSat WiFi Gateway modem/router. I also have the VOIP phone service. Everything (internet and phone) works fine until I put the gateway into bridge mode. As soon as I do that (and it reboots), the phone service cuts off. When I turn off bridge mode on the gateway and reboot, the phone service comes back. I've done this 3 or 4 times now with the same result. I want to use bridge mode so that I can use my own router (pfSense), but obviously also need phone service. Has anyone else experienced this? I've emailed ViaSat support, but no response yet. Thanks!

Hi Brad,

I spent an hour on the phone with ViaSat tech support earlier today and at the end all they could do is promise to have someone call me back. The support person did say that it should not be cutting off phone service in bridge mode.

Following up on the above post...30+ hours and still no callback on this issue from a ViaSat Voice tech expert as I was promised. Was told it would be ASAP (like in a few minutes).

I didn't bridge my modem.....I just hooked up my Netgear router and everything works just fine. Am I missing something here?...does bridging the modem supposedly give better speeds or something?

I have used several different routers with my SB2+ modem and have never had to use the bridging function.  I think that maybe some have run into some problems with NAT with two routers in the system.  May be related to IP address conflicts.

Didn't that create a double-NAT for you Andy? Do you do any port redirection? I would think that would be problematic.

Didn't have a problem at all....although I was suspicious at first. My VS1 system is the non-wifi modem so of course it worked but I wasn't sure what to expect with the Spock modem. I've done several test, switching back and forth between the built-in router of the Spock modem and then my Netgear, I can discern no difference.

Andy, do you use Google voice in bridge mode?

I just want the ViaSat gateway to pass thru all traffic to my router and reveal the public IP address to it. All the NAT, port forwarding, DHCP, etc. would be done by my router. I was never able to do this with the old Exede Wifi Modem, but supposedly it can be done with the new ViaSat Wifi Gateway in bridge mode. Unfortunately, it's turning off my phone service when I put it in bridge mode.

Sounds like a bug or design fault of the new viasat2 modem.
I am a long time pfsense user, been running it over 10 years now. Also run it at the colo for my site. You wouldn't happen to have Google voice do you? Would love to have you see if the new viasat2 modem will crash in bridge mode with you on an edge case.

Yeah, I've been using pfSense for about 8 years now in multiple locations. Before that I used SmoothWall and IPCop for many years. Just gives you so much finer control over your network than simple wireless routers. I do have Google Voice.

if I have gmail open and hangouts on in gmail, with also the same google voice number on one of my android devices....an incoming google voice call will ring both devices as soon as i answer from one device the viasat modem in bridge mode drops all traffic. I can cause this over and over but viasat blames my routers. but i can get it to do it with pfsense, ubiquiti, and others....viasat actually gives you a few public ip's in bridge mode. check out the netmask assigned by dhcp. or just plug in a switch to the first port on you vs2 modem and plug in another router....also you "ip" seems to live on the gateways and that traffic is nat'ed to you modem.....aka bridge mode is never true as the ip's live off of the modem. I am dumbing this down but i suspect this is whats going on from my testing.

Very strange! Man, that sucks. Why on earth does ViaSat make it this difficult? I've used dozens of different cable, T1, fiber, etc. modems and never had these issues. It was always easy as pie setting up my own gateway router..
