Hello, I'm Liam. I'm having some issues with a pptp vpn that i've setup. The vpn connects, gets an ip, all ok. But data transfer is slow - 5 - 9kb/s. The vpn is on my local internet connection, but I've got a 1meg upstream, 5meg down. I even tested it locally using my 100meg LAN, but it still runs at 5-9kb/s. This is starting to bug me! I've googled, but most people have slow actual link's, not VPN's. Any help is much appreciated, Many Thanks, Liam. PS: I'm running debian 4.0, if that was anyone's next question
Qos? Hello Liam.... this is weared... I have a similar setup which just runs fine (let's say as well as it can..) It looks like you some QOS based management badwidth setup!? (you or your ISP)
Hmm Thanks for the reply, I dont think my isp would do that to me though I tested it on my LAN locally anyway, and it's still really slow. Perhaps i'll try removing MPPE-128 encryption. Thanks, Liam.
mppe well I never heard about mppe slowing down the transfert rate through thr tunnel but you can try. Right! does dmesg or the debug options of both pptp and pppd tells something interesting? Maybe you can try to adjust your mtu / mru (using ping -s XXXX <point-to-point host>)
Hi, The connection seems to run fast at first, then drops down to these speeds. Ping times are good 0.168... But actual data throughput is bad... Actually this time, the vpn has just stopped completely, it downloaded about 200k of the test file, then slowed down to a complete stop. This is starting to bug me now... I might have to lookup other vpn solutions... Thanks, Liam.
did you trydisabling mppe encryption? if it can help, here is my pptp.conf and ppp option file: pptp.conf################## option /etc/ppp/pptpd-options debug logwtmp bcrelay eth2 localip 10.250.0.220 ######################### ppp otion file############### plugin radius.so plugin radattr.so name pptpd refuse-pap refuse-chap refuse-mschap require-mschap-v2 require-mppe-128 ms-dns 10.250.0.15 ms-wins 10.250.0.2 proxyarp nodefaultroute debug lock nobsdcomp ########################
I tried the no mppe, but it didnt help at all Thanks for your config file, mine appears almost identical, well, except the radius authentication. I'm looking into an IPSEC tunnel now, we'll see how that goes perhaps... Thanks for your help, it's much appreciated. Liam.
