In my Radius config on the server, got rid of
Framed-Compression = Van-Jacobsen-TCP-IP,
in /etc/ppp/ppp.conf
vjcomp (from the man pages)
Default: Enabled and Accepted. This option determines if Van
Jacobson header compression will be used.
vjcomp disabled

Not sure on FreeBSD, but on my Cisco where all the PPPoE sessions are
terminated as L2TP tunnels, I see
bell-border#show int vi426 confi
Virtual-Access426 is an L2TP link interface
Building configuration...
interface Virtual-Access426 configuration...
mtu 1492
ip unnumbered Loopback0
ip tcp header-compression
before
and after
bell-border#show int vi426 confi
Virtual-Access426 is an L2TP link interface
Building configuration...
interface Virtual-Access426 configuration...
mtu 1492
ip unnumbered Loopback0
In this case, I am not sure where the fault lies... In the Cisco, the ERX
or FreeBSD, or PE. The ERX initiates the tunnel to the Cisco. At that
point, I would have thought that they would properly negotiate
capabilities... Not sure, but this did indeed solve the problem, and the
ERX according to the article does not support VJ Header compressions.

pppstats works for me
