Just a bit more information which might help clear things up: If I ping from 192.168.1.3 to 192.168.1.101 and leave it going - ALL my traffic from the XP box to the LAN works fine (in moderation). For example - as long as the server is pinging me (just a standard "ping -t 192.168.1.101") I can ping the server without any problems (even with -l 1500). I can surf the web even and no received errors are shown. That is until I download a 500mb file and then it starts to chug running at 254KB/s on a 10Mbit lan - although the pings to the XP box keep going and only get 1-2% "No buffer space" errors - but the errors 45mb into the file are up to 1350. Shed any more light? (Im just dreaming up random test scenarios) BTW: Heres my mpd.log (left running through all the tests, not shut down) Sep 9 10:25:20 armadillo mpd: mpd: pid 26273, version 3.14 (root@armadillo.lan.eorigen.com 10:05 9-Sep-2003) Sep 9 10:25:20 armadillo mpd: [pptp0] ppp node is "mpd26273-pptp0" Sep 9 10:25:20 armadillo mpd: mpd: local IP address for PPTP is 82.68.60.9 Sep 9 10:25:20 armadillo mpd: [pptp0] using interface ng0 Sep 9 10:25:20 armadillo mpd: mpd: pid 26275, version 3.14 (root@armadillo.lan.eorigen.com 10:05 9-Sep-2003) Sep 9 10:25:20 armadillo mpd: [pptp1] ppp node is "mpd26273-pptp1" Sep 9 10:25:20 armadillo mpd: [pptp5] ppp node is "mpd26275-pptp5" Sep 9 10:25:20 armadillo mpd: [pptp1] using interface ng1 Sep 9 10:25:20 armadillo mpd: mpd: local IP address for PPTP is 80.177.231.130 Sep 9 10:25:20 armadillo mpd: [pptp2] ppp node is "mpd26273-pptp2" Sep 9 10:25:20 armadillo mpd: [pptp5] using interface ng5 Sep 9 10:25:20 armadillo mpd: [pptp2] using interface ng2 Sep 9 10:25:20 armadillo mpd: [pptp6] ppp node is "mpd26275-pptp6" Sep 9 10:25:20 armadillo mpd: [pptp3] ppp node is "mpd26273-pptp3" Sep 9 10:25:20 armadillo mpd: [pptp6] using interface ng6 Sep 9 10:25:20 armadillo mpd: [pptp3] using interface ng3 Sep 9 10:25:20 armadillo mpd: [pptp7] ppp node is "mpd26275-pptp7" Sep 9 10:25:20 armadillo mpd: [pptp4] ppp node is "mpd26273-pptp4" Sep 9 10:25:20 armadillo mpd: [pptp4] using interface ng4 Sep 9 10:25:20 armadillo mpd: [pptp7] using interface ng7 Sep 9 10:25:20 armadillo mpd: [pptp8] ppp node is "mpd26275-pptp8" Sep 9 10:25:20 armadillo mpd: [pptp8] using interface ng8 Sep 9 10:25:20 armadillo mpd: [pptp9] ppp node is "mpd26275-pptp9" Sep 9 10:25:20 armadillo mpd: [pptp9] using interface ng9 Sep 9 10:25:42 armadillo mpd: mpd: PPTP connection from 82.68.60.10:3065 Sep 9 10:25:42 armadillo mpd: pptp0: attached to connection with 82.68.60.10:3065 Sep 9 10:25:42 armadillo mpd: [pptp0] IFACE: Open event Sep 9 10:25:42 armadillo mpd: [pptp0] IPCP: Open event Sep 9 10:25:42 armadillo mpd: [pptp0] IPCP: state change Initial --> Starting Sep 9 10:25:42 armadillo mpd: [pptp0] IPCP: LayerStart Sep 9 10:25:42 armadillo mpd: [pptp0] IPCP: Open event Sep 9 10:25:42 armadillo mpd: [pptp0] bundle: OPEN event in state CLOSED Sep 9 10:25:42 armadillo mpd: [pptp0] opening link "pptp0"...
