Hi guys
I use pppoe on my openbsd based router some time now, but always using
user space ppp. I read on several posts / blogs / etc. that kernel-level
pppoe (pppoe(4)) would have better performance and I decided to bring up
a test device.
My config (OpenBSD 4.6):
/etc/hostname.pppoe0
inet 0.0.0.0 255.255.255.255 NONE \
pppoedev vr0 authproto chap \
authname 'user' authkey 'pass' up
dest 0.0.0.1
/sbin/route add default 0.0.0.1
And additionally in pf.conf:
match on pppoe0 scrub (max-mss 1440)
And finally in sysctl.conf:
net.inet.tcp.mssdflt=1440
The connection establish and icmp does work, but with udp pings I got
duplicate answers and tcp does not work at all. Short: the connection is
not usable.
On the same device using userspace ppp:
/etc/ppp/ppp.conf
default:
set log Phase Chat LCP IPCP CCP tun command
pppoe:
set device "!/usr/sbin/pppoe -i vr0"
set mtu max 1492
set mru max 1492
set speed sync
disable acfcomp protocomp
deny acfcomp
set authname "user"
set authkey "pass"
set dial
set login
add default HISADDR
Everything works ok.
Did I miss anything here?
Any help would be appreciated!
Regards André
