adsl and ppoe
« on: September 12, 2002, 06:31:03 PM »
I have adsl using a westel wirespeed modem/router. when i connect the internal nic to my linksys hub it cannot access the net. i turned dhc off in the westel setup so e-smith 5.1 can supply dhcp....still no connection.  i ran through the e-smith setup and set it to use ppoe with username/passwd.  my question is...should i have to point the e-smith box to the westel router is some way to get out to the net? or is it something i am not following.  any help would greatly be appreciated.

Why would you use PPOE if you already have a router?  The E-Smith machine should be configured to accept an IP Address similar to the one handed out by the westel router.  Configure E-Smith's default gateway to be the IP Address of your westel router.

Lets assume the following:
Westel Router:  192.168.1.1/255.255.255.0

E-Smith machine should be configured:
IP Address:  192.168.1.2
Subnet:  255.255.255.0
Default Gateway:  192.168.1.1

Hope this helped,
Nathan

Just went through this config last night.

The ethernet port on your westell should be 192.168.1.254 out of the box.
Load a web browser and hit that address. You should at that point get a screen that will allow you to insert your account name and password. You can at that point put in that information and you should be flying assuming that all of the devices on your network have an address of 192.168.1.x, mask of 255.255.255.0 and gateway/dns are pointing to the westell.

I didn't want the westell routing and NATing. So I did the following:
On that initial screen of the westell there are some buttons to the left. If memory serves the bottom button says something like "expert config". In there you will find a screen that says something like "vc config". You will notice that VCI/VPI 8 and 35 are set to PPPoE. Change PPPoE to Bridge. You might want to make sure that NAT is disabled on the westell as well. You will find that under LAN.

Once you reboot your westell will no longer route it will bridge traffic.
At that point you will want to make sure that you have two NICs in you sme server and it is indeed acting as a true firewall. Configure it to do PPPoE and put in your account info.

That should be it in a nut shell.

Sorry for being a little vague on the westell config. I am running from memory.

Because you can avoid many NAT and port forwarding problems if you use the "router" simply as an ADSL modem. Just look at all the recent traffic on these boards and you can see the problems people have with routers.

It's also desirable for security reasons to run the server in server&gateway mode - you can completely segregate internal and external traffic in s&g mode.
