routing FTP, RDP, and VPN traffic thru 2 routers.

Our current vonage setup has our home router in front of our vonage adapter, however we've had some service inconsistencies and we'd like to setup our phone adapter in front of our home router so it can prioritize voice traffic. however, there is also an FTP server and RDP connections made to a system inside the network, and will soon be an IPSec VPN tunnel as well, and we're having issues setting it up to pass through the phone adapter.

Our current setup is as follows

We have Comcast cable and a motorola SB5100. Connected to that is a Linksys BEFSX41, which has port forwarding configured for FTP traffic and RDP traffic (this will also be used for the VPN, as it supports IPSec). Behind the Linksys is our Motorola VT1005V Voice Adapter/Single port router for the vonage service, which we have 2 phone lines connected to.

I had assumed that we could just hook the Motorola phone adapter directly to the cable modem, and then enabe the DMZ on the motorola and put the Linksys in the DMZ. However that doesn't seem to work. very well. or at all. Internet connectivity and phone service is fine, but outside connections cannot be made to the FTP or RDP servers.

Now, the VT1005V is hardly configurable, but I thought the DMZ would allow traffic to pass, but it seems as though it doesn't make any difference. So my next thought was to disable the Motorola's DHCP, but to do that you also have to disable NAT, which we'll need in order to get outside. so that is out.

Is there something I'm missing, or do we need to get a more configurable, all-in-one device, and does such a device exist? I need port range forwarding, IPSec VPN support, voice prioritization and support for 2 phone lines.

Before doing anything, I would investigate the BEFSX41's ability to do QOS (Quality of Service), and leave your setup exactly the way it is. If QOS is available with newer firmware, you can selectively allow voice traffic to get more bandwidth, hence you requirement for prioritization. If your other services are working fine with your current setup, I'd leave well enough alone, and not tax the Vonage device too much. They aren't very good at routing, switching, or networking in general. They are good phone adapters and you can leave it that way.

will do, thanks for the tip. what ports does voice traffic use?

*edit* actually just went and flashed to the latest firmware, and yes, it does have QoS now Cool

it gives me several options. I can specify either HIgh or Low priority by either choosing the ethernet port that the phone adapter is connected to, or by specifying the phone adapter's MAC address,

i can also specify high, med high, med, med low, and low priority to 3 specific incoming ports (maybe more, not sure)

i'm assuming that by MAC or Ethernet port will be the preferred method, correct?

Not sure on that, sorry, but the way my WRT54G is, I can set priority according to physical Ethernet port on it. So my Vonage is on Port 3, I give that port a higher priority than 1,2, and 4.

heh, i was editing the same time you posted. looks like QoS is the same way for mine as well. we'll see how it does. thanks!

No problemo, hope it works out. If not, let us know. There is a certain member here named NateHoy who is the QOS guru. He can help as well if you run into issues.

well, we're still having substantial problems. tried several different configurations with the phone adpater and our router. currently the phone adapter is in the DMZ and has priority over all other devices on the network, but were still getting an awful lot of choppiness during phone calls at times.
