Pptp mtu
The Maximum MTU for PPTP tunneling VPN using Ethernet in Windows 9x/ME is 1462. In Windows XP/2k/2k3, it seems to be limited to 1400 by default. See this Microsoft article for changing the Max MTU value in Windows XP/2k/2k3: MS KB 826159 You can make a custom shell script at this address : /etc/network/if-up.d/set-pptp.sh, #!/bin/sh if [ "$IFACE" = "ppp0" ]; then ifconfig ppp0 mtu 1200 fi finally make executable like so: $ sudo chmod 755 /etc/network/if-up.d/set-pptp.sh It's not working, I diconnect and connect again but still shows 1400 mtu size – Mohse Taheri Aug 25 '15 at 6:26 @MohseTaheri: You will have to look into the PPTP config file ( /etc/pptpd.conf ) to see what file is defined for the option setting. PPTP (GRE): 40 bytes The MTU outside the tunnel minus the summed overhead is the MTU inside the tunnel (unless the tunnel streams packets end-to-end, then the MTU depends on the tunnel parameters). When bridging packets PPP tunnel need to pass packets with Layer-2 (MAC) header included , so default interface MTU (in case of pptp it is 1460) is not sufficient for this task.

故而，PPTP over PPPoE的準確MTU值是 1436，L2TP over PPPoE的準確MTU是1452。別人說的 1400 偏保守了點。 如果你用 ADSL 上網，然後用 PPTP 來翻Wall，那麼，你實際上是 PPP 協議跑在 TCP 協議上再跑在 IP 協議上再跑在 PPP 協議上再跑在 IP 協議上再跑在以太網協議上。 Hit https://nordvpn.sjv.io/c/376211/570073/7452 & set up NordVPN PPTP on your own Mikrotik today!

PPP connections are connections such as modem connections, Integrated Services Digital Network (ISDN) connections, or direct cable connections over null serial cable or over parallel cable. VPN connections are Point-to-Point Tunneling Protocol (PPTP) connections or Layer 2 Tunneling Protocol (L2TP) connections. I have a M$-based VPN connection that I connect to every so often. After connecting to the VPN server, I need to run sudo ifconfig ppp0 mtu 1200, So that I can log on to the server, or else ssh client will respond with expecting SSH2_MSG_KEX_DH_GEX_GROUP.. I want to store this mtu setting persistently so I do not have to run that command everytime I connect to the VPN. Compare your Top 3 Mtu For Pptp Vpn VPN Providers.

24/12/2017 PPTP can be used with most firewalls and routers by enabling traffic destined for TCP port 1723 and protocol 47 traffic to be routed through the firewall or router. PPTP includes PPP authentication and accounting for each PPTP connection. Full authentication and accounting of each connection may be done through a RADIUS client or locally.
