MPD 3.13 PPTP server MTU problems & questions

Hello,

I've been running a FreeBSD 4.7 box with a MPD 3.13 PPTP VPN server for 
quite some time now and, altough it mostly works, I'd like to iron out 
some problems we encounter.

Configuration (that gives an IP address in a 192.168.0.0/24 local 
network to 16 Win2k clients at this moment) is done according to the 
following model :

MPD PPTP, DNS & Samba server is 192.168.0.10

mpd.conf
*****************************************
default:
         load pptp0

pptp0:
         new -i ng0 pptp0 pptp0
         set iface route 192.168.0.10/24
         set iface disable on-demand
         set iface enable proxy-arp
         set iface idle 3600
         set bundle enable multilink
         set link yes acfcomp protocomp
         set link no pap chap
         set link enable chap
         set link keep-alive 10 60
         set link mtu 1460
         set ipcp yes vjcomp
         set ipcp ranges 192.168.0.10/32 192.168.0.204/32
         set ipcp dns 192.168.0.10
         set ipcp nbns 192.168.0.10
         set bundle enable compression
         set ccp yes mppc
         set ccp no mpp-e40
         set ccp yes mpp-e128
         set ccp yes mpp-stateless

******************************************


mpd.links
******************************************
pptp0:
         set link type pptp
         set pptp self 192.168.0.10
         set pptp enable incoming
         set pptp disable originate
******************************************


As you'll see in the logs below and from ifconfig output, altough the 
ngX interfaces MTU is set to 1460 with "set link mtu 1460", it stays at 
  1500. Any idea why ?

My other problem (maybe related to the previous one ?) is SMB browsing :
PPTP clients connected through the VPN can see but not browse all the 
other machines on the local network. The only one that can be browsed is 
the one also hosting the PPTP server : routing problem ?


By the way, is there a way to reduce mpd's log verbosity ?


Thanks for your time & help.

Regards,
