Hi All,
I had implemented in my network pppoe with userman but after some time I could observe many disconections of pppoe sesions. From customers side it looked like short dc.
I’ve moved back to simple DHCP solution with vlans (pppoe was on vlans also) and it keep working fine.
Few days ago I’ve installed freeradius on some linux machine at home and connected my MT to it.
I took 3 sample customers and moved them again to pppoe using freeradius and guess what, again dc 
pppoe profiles:
1 name="profile_3m" local-address=192.168.3.1 remote-address=pppoe_3m
use-mpls=no use-compression=no use-vj-compression=no use-encryption=no
only-one=yes change-tcp-mss=yes address-list=""
dns-server=195.88.90.3,195.88.90.4
5 name="profile4-8" local-address=10.1.0.1 use-mpls=no use-compression=no
use-vj-compression=no use-encryption=no only-one=yes change-tcp-mss=yes
address-list="" dns-server=192.168.0.1,195.88.90.3
pppoe-server:
4 service-name="INTERNET_8M" interface=vlan_220_piastowska_5_data
max-mtu=1480 max-mru=1480 mrru=disabled
authentication=pap,chap,mschap1,mschap2 keepalive-timeout=10
one-session-per-host=yes max-sessions=0 default-profile=profile4-8
8 service-name="INTERNET_3M" interface=vlan_22_kasztanowa_2 max-mtu=1480
max-mru=1480 mrru=disabled authentication=mschap2 keepalive-timeout=10
one-session-per-host=no max-sessions=0 default-profile=profile_3m
and here how looks this dc in log:
16:53:58 pppoe,ppp,info,account username logged out, 7352 440968 261254 7355 2976

16:54:11 pppoe,ppp,info,account username logged in, 10.1.0.2
is there any way to make pppoe work on MT ? maybe I have some wrong settings?
Thanks in advance!
