St Thomas, ON | BEFSR81: What setting to use when modem is PPPoe? The modem I have is Speedtouch 516. I've set it so that it does PPPoe. I was having too many problems lately with it in bridge mode and having the router do the PPPoE (getting lots of "can't connect to PPPoE server" error messages).
The router is Linksys BEFSR81. It's LAN address is 192.168.1.1.
The modem is now doing PPPoE, and the modem's LAN ip address is 192.168.1.254. But I don't know what mode to set the router. My options are:
- Obtain IP address automatically
- static IP
- PPPoE
- RAS
- PPTP
- Heart Beat Signal
So which one do I use? I assume I can't use PPPoE (since that modem is now doing that).
If I choose "obtain IP address automatically" then if I want to hard-code the IP address and gateway of my network devices, how do I do that?
I basically still want the router to be the gateway for all network devices, and for it to continue to have 192.168.1.1 IP address, but I just don't want it to be doing the PPPoE login any more. |

said by sm5w2:I was having too many problems lately with it in bridge mode and having the router do the PPPoE (getting lots of "can't connect to PPPoE server" error messages). This indicates you are set to "connect on demand". I suggest selecting something else.
said by sm5w2:The router is Linksys BEFSR81. It's LAN address is 192.168.1.1. And the netmask is probably the standard 255.255.255.0. This means the modem at 192.168.1.254 and with the same probable netmask 255.255.255.0 is in the same network address space: 192.168.1.x. This is important later.

If I choose "obtain IP address automatically" then if I want to hard-code the IP address and gateway of my network devices, how do I do that? With router WAN connected to modem, either "Obtain... Automatically" (easiest, find what it gets in the routers's STATUS page) or "static IP" should work. BUT...
The router and modem cannot work this way if they are in the same network. One MUST change.

OK, since one must change the modem has just been selected.  If you need a suggestion, change modem to 192.168.0.254 netmask 255.255.255.0.
But you will be in a condition often called "double NAT". There's a Network Address Translation (NAT) from 192.168.1.x to 192.168.0.x to your public address. Lots run this way and never run into the limitations. I sense you may know some of them.
Hope this helps. |
