Westell 2200-15 Modem Verizon

Just replaced my four year old modem only with a Westell 2200-15 Router/Modem from Verizon. I'm new to routers and don't understand the terminology used. Two questions:

1. Default VC configuration came as PPPoE. Does this mean it's in router mode?

2. The other configuration I've seen mentioned is Bridge mode. What's the difference between PPPoE and Bridge modes and is one better than the other for my setup?

My system is a stand alone computer, no network or sharing running Win XP Pro SP1.

you want the ppoe router mode for security you have the router protecing your pc also you have the modem log on and off then net for you.

Where as if you left in bridge mode you would have to use ppoe client to get on the internet and maybe a software firewall for security.

To some it up in router mode it's all hardware doing the work for you less software installs/configurations

I hoped that made sense to you.

The router mode gives you a hardware firewall protection....NAT. You can use it for a single computer, since that 2200 has a single ethernet LAN port...or you can uplink that LAN port to a switch (or an old hub) to share you connection with more computers.

Notice the IP address of your computer is something like 192.168.1.47? That's a private IP address, not pingable from the internet. That's the devices NAT router protecting you.

The device in that mode also supports PPPoE authentication for you...so you don't need to install some 3rd party software to log in with your ISP.

Today I worked on one of those modems, and had to switch it to bridge mode, because the clients satellite office I was working on needed to use a special router...which provided their PPPoE login, and their NAT firewall...so I disabled the router and PPPoE of the 2200...using it pretty much just as simple DSL modem, which is what "bridged mode" really is. Plugging a computer into the ethernet port of thise device when it's in bridged mode...you have no firewall protecting you...the IP address that your computer gets is a public IP address, and you're open for troubles that way.

i have the westell 2200 and a wireless router and i am having difficulty port-forwarding through both firewalls. does anyone have any advice on how to do this? do i need to set the modem up as a bridge and use pppoe software?

you should keep the modem in bridge mode if you are using another router the router can handle the login in process so you don't need any software based ppoe clients. Your double natting with both in router mode but modem in bridge...

also this might help clear up the port mapping http://practicallynetworked.com/sharing/specialapps.htm

I would also read the static ip guide below me follow that and then do the portforwarding it makes it a little more eaiser..

This how port forwarding work i'll give you an exmaple say you use yahool messeager to get that work you goto find out what ports the link shows you that and what computer do you want to have that access so if you do the static ip gave your computer and adress or 192.168.1.13.

You would go into port forwarding section of your routers page then type Yahoo Messenger Chat
IN TCP 5000 - 5001 usually there is box next to it for that computers adress in case it would be 13 or some router it's 192.168.1.13

I hope that helps
