[Cerowrt-devel] Anyone using PPPoE with Sugarland?

Hello,

I am experimenting with using Cero/Sugarland on a PPPoE connection, and can't seem to find a config of simple_qos that works well.

The service is DSL, PPPoE, 3M/768K. Without any qos, the router works well, as expected. When I try to use simple_qos, the clients have trouble loading websites (hangs while loading, etc).

Netlyzer shows upstream buffering of about 650ms, consistently. I have tried various higher and lower values for UPLINK and DOWNLINK, but nothing seems to help. Anyway, I think 15-20% below link should be fine.

Here is my config:
UPLINK=550
DOWNLINK=1900
DEV=ifb0
IFACE=ge00
DEPTH=42
TC=/usr/sbin/tc
FLOWS=8000
PERTURB="perturb 0" # Permutation is costly, disable
FLOWS=16000 # 
BQL_MAX=3000 # it is important to factor this into the RED calc

CEIL=$UPLINK
MTU=1492
ADSLL=""
PPOE=yes

Couple of things I am unsure about:
1) Should the IFACE be ge00 or pppoe-ge00?
2) Should the MTU be the pppoe mtu (1492) or the ethernet (1500)

One last thing: I have the lan split up into VLAN interfaces se00.1, se00.100, and se00.200. Everything otherwise works as expected with these, but could the naming be breaking something?

If anyone is willing to share a working configuration it would be much appreciated.

Thanks,
Bill Katsak
