PPPoE not working on RV345

Peter Elbertse · ‎10-06-2018

Hi all,

I've bought a Cisco SB RV345 for a client that wants to provide internet to some building management devices.

For this purpose we've setup a RV345 using two WAN connections.

WAN1: PPPoE connection over a 4 Mbps Fiber VLAN (connected to a Cisco ASR920 provided by Tele2)

WAN2: Static routed back-up connection over 30/3 Mbps VDSL (connected to a Cisco 887VA router)

My WAN2 connection (that is supposed to be used as back-up connection) does work.

My problem is the PPPoE connection does not seem to work (it doesn't get connected and IPv4 is shown as 'down').

What I've tested:

- Setup the PPPoE on WAN2 interface (did not resolve the issue)

- Tested on Firmware 1.0.01.18 and 1.0.01.17 (no success)

- Connected my Win10 laptop to the ASR920 and setup PPPoE on my laptop (this did work)

The logs of the RV345 don't tell me much either:

Any help or suggestions would be appreciated.

Hello

Try to setup PPPoE for both IPv4 and IPv6. It seems to help in my case.

Peter Elbertse · ‎10-15-2018

I've tried to setup PPPoE on IPv6 as well, but no success.

Based on Cisco TAC Feedback I've also tried to set MTU to 1492 or 1472; both without success.

I did notice that the port on the CPE is configured as 100 Mbps Full Duplex; but when I set the RV345 to these settings, I don't get a link (I do when I set the port to 100 Mbps Half Duplex, or Auto Negotiate).

Kind regards,

Peter
