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.

protocol IP on link -1 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, --Yann
