I have ATT DSL provider with Westell 6100 modem. I want to bridge the modem to the sonicwall. I beleive the step is straight forward but appears my software for the modem is different than most because the modifications needed are just not available when I interface the modem. He is what was recommended when searching the net.

Click Edit for the row that has "PPPoE" in the Protocol column and "Enable" in the Status column.
Select Bridge from the dropdown list for the Protocol field.
Verify that the Mode field is also set to Bridge.


My only option is go to screen where it has  PPP is on the modem button or PPP is on computer,gateway,router,etc.
My question is that if I check PPP  is on (router,gateway,computer)do I need to put the username and password for the dsl number in the sonicwall(VPN) PPPoe screen even I thought I put the same in the modem? Also, Would I just need to but NAT enabled in sonicwall using the gateway IP provided by ATT?

I would not modify the Westel modem if it is presenting an external IP address. It most likely is setup with DHCP so you could either let the SonicWall use DHCP on the WAN side or hard code the actual ip/subnet/gateway on the WAN port of the SonicWall. In any event, let the SonicWall do the NAT translation for your LAN.

This should work very well with a good level of security.

One thing i cannot ping or access the modem/gateway remotely though the internet is up.

The Westell modem can be configured to disable (Internet Control Message Protocol) ICMP.
This is the protocol that utilities like ping use for troubleshooting network issues. Once your network is configured, it is not a bad  idea to disable ICMP because that makes it just a little more difficult for hackers to know that you exist.

If you have the login username/password for the modem (not the same as the PPPoE credentials) you can enable/disable ICMP as you need to.

If you login to in locally (from the LAN), you can enable remote management.
