linksys wrt120n PPPoE client issue

RouterOS General
1

I have several routers running PPPoE servers to internet connections to ubiquiti radio and other
home routers like TP-Link using the inbuilt PPPoE clients without any issues. Yesterday I was
setting up a linksys wrt120N PPPoE client and it dails in fine but doesn’t allow for internet to
go through on digging around I notices the routes were wrong. the one pointing to the internet
was dst add 0.0.0.0 gateway was local IP assigned by the PPPoE server instead of the remote
IP on the Router. The PPPoE server dishes out IPs from 172.16.2.10-172.16.2.254 with the its
IP 172.16.2.1. Is this a problem with the linksys 120N or my PPPoE setup?

Two questions:

  1. Are you injecting routes when the PPPoE session is established
  2. Are you authenticating locally or via RADIUS

Dynamically added routes in PPPoE can cause a lot of problems if they aren’t correct.

We have had same issue with several of the linksys routers connecting to MT pppoe servers. We found that if chap was enabled on the server profile, the pppoe session would dial in but no traffic would pass - disabling chap forced the linksys to use PAP and they worked fine.

I will have to try that and see if it worked but the problem is that pap is not secure and am not sure it will work with the existing ubiquiti radios using pppoe.

Am not injecting any routes just the default gateway.

I finally managed to get the linksys to work by avoiding mschapv1 and v2 it works fine with pap and chap.
