Problem with Mikrotik + RADIUS + PPPoE

RouterOS General
1

Hello, I have a RADIUS server doing authentication and accounting with ADSL and with wireless users. The wireless users are connected to a MikroTik which is running a PPPoE server. There are absolutely no problems with the ADSL users, but the PPPoE users are constantly losing their connections and then reconnecting. En average, the length of sessions varies between 1 and 10 minutes and most times shows “Acct-Termination-Cause = User-Request”.
I’ve checked the status of the wireless link but everything seems to be right. There are other wireless users in the same neighbourhood and some of them have this problem and others do not.

Thank you very much for any suggestions you can provide.

post config you can try lowering mtu maybe 1460 might help that made a LARGE DIFFERENCE for my clients dropping on and off

Thanks.
Should I set the MTU using the RADIUS server or in the MiktoTik PPPoE server?

set it in the pppoe server in the the mikrotik

OK, I’m going to try this.
Nevertheless, a fact that catches my attention is that when these users gets disconnected repeatedly, the FreeRADIUS server shows “User-Request” as the termination cause. Any idea of why?
Thanks again.

also if you get User Request thats a Admin
Quit command issued from the command line interface or script on radius box.
more importantly what does the mikrotik tell u when they drop off best to look there as well
18:35:43 pppoe,ppp,info,account user1 logged out, 43785 7936392 59008336 42659 58738
18:35:43 pppoe,ppp,info : terminating… - peer is not responding
18:35:43 pppoe,ppp,info : disconnected
example above is a client with a break in there connection

I am getting a similar issues with pptp remote laptop (authenticated to Windows Server 2008) but no problem with a MT router.

echo: pptp,ppp,debug <cl.ie.ent.ip>: LCP missed echo reply
echo: pptp,ppp,debug,packet  <cl.ie.ent.ip>: sent LCP EchoReq id=0x4
echo: pptp,ppp,debug,packet     <magic 0x17f25004>

This was a problem with Active directory settings. (of which I know nothing, our windows nerd fixed it)

I have the same issue.
My 1000+ users getting randomly connected disconnected and they have been complaining about this since 15 days.

Free radius error shows USER REQUEST.

Microtik says, LCP missed echo reply.
