problem disabling acfcomp and enablign lqr

[RJ45 <rj45_(_at_)_slacknet_(_dot_)_com>]

I Am tweaking my ppp.conf file
this is actually my ppp.conf:

default:
 set device "!/usr/sbin/pppoe -i hme0"
 set speed sync
 set mtu max 1452
 set mru max 1454
 set timeout 0
 set authname  username
 set authkey ********
 set log local Phase tun command debug
 set dial
 set login
 delete all
 add default HISADDR
 enable tcpmssfixup 

I had to remove the following lines otherwise I never ca nestablish a
pppoe connection:

disable acfcomp protocomp ipv6cp
deny acfcomp
enable lqr mssfixup dns
accept lqr

the strange thing is that every example I Saw around does have lpr enabled
and acfcomp explicitely disabled. If I Try to disable acfcomp and enable
lqr I won't be able to succesfully establish a pppoe connection looks like
my ISP works like that.
I wanted to ask waht are the possible improovements disabling acfcomp and
enabling lqr since looks like I Cannot set tham as I Would ??

anyone else ahd my problem?

thanks

Rick
