Well, I also do AAA to another box with FreeRadius but, indeed, I think
that that load is coming from all those PPP sessions to take care of, am
I right? someone can share your opinions here?

This is my mpd.conf
...
pppo800:
new pppo800 PPPo800
set ipcp ranges a.b.c.d/0 192.168.8.38/32
load stand
stand:
set bundle no multilink
set bundle enable compression
#set bundle accept encryption
#set bundle enable crypt-reqd
set bundle max-logins 1
set iface idle 3600
set iface disable on-demand
set iface enable proxy-arp
set iface enable tcpmssfix
set ipcp no vjcomp
set ipcp dns a.b.c.d a.b.c.e
set link no pap callback acfcomp protocomp
set link yes chap chap-msv2 chap-msv1
set link max-redial -1
set link keep-alive 4 10
set link mru 1300
set link mtu 1300
set ccp yes mppc
set ccp yes mpp-compress
#set ccp yes mpp-e40
#set ccp yes mpp-e128
set ccp yes mpp-stateless
set radius server a.b.c.d testing123 1812 1813
set radius retries 3
set radius timeout 3
set radius acct-update 60
set iface enable radius-session
set ipcp enable radius-ip
set bundle enable radius-auth
set bundle enable radius-acct
Now that I see it, compression is enabled but it fails to negociate,
have no time to investigate now ...
Bye,
Ezequiel.
