I should mention that we are using both PPPoE (Wireless Network GAteway) and L2TP (Forwarded from Bell DSL Network) servers on 2 different routers.

When using Radius to authenticate PPPoE users, is there a way to ensure that Only One session can exist? If we use secrets and select a Profile with "Only One= yes" then the router refuses the second request for a connection, however if we are using an External Radius server, the "Onl...

Any solution to this issue? Running 3.25 and if router get's rebooted, graph history is lost? Using a PC graph history is saved even after shutdown. We have a 2 GB CF in the RB1000.

GREG3f

Is an RB450 powerful enough to be used as a Dude server for 5 Class C networks? It would be installed at the gateway and monitor aprox 500+ IPs? This is for a WISP setup.

If not, which RB could do this or what PC config would be adequate?

GREG3f

Bad News. Port 2 dropped all incoming traffic once again and required reboot to resolve it.

Going to prepare a P4 PC with 3.13 and see if the same problem persists with my config. Should help me decide if it is the RB600 or the ROS that has issues.

GREG3f

2d 2h and still going without issue. Think I will stick with 3.13 until another lockup happens.

GREG3f

So far so good... knock on wood!

Up 1d 18h since reboot with no lockup using 2.18 Firm and 3.13 ROS.

See we now have 3.17 as stable download... tempted to give it a try and add back queues etc?

GREG3f

UPDATE. Despite having removed queues, a port has locked up once again. This time it was port 3 rather than port 2.

I had uploaded 2.18 file and now since the RB600 locked again, I was forced to restart and am now running 2.18 firmware.

Will see if 2.18 is any better.

GREG3f

I was using 5 Simple PCQ queues and after reading another thread decided to remove all simple queues. So far, no lock up, but it is still early to point the finger at PCQs. Will report back later.
