PfSense blocking more than one client to connect to a remote Windows VPN server



  • Hi everyone,

    I have a Windows 2008 R2 in a datacenter which is serving as my VPN server for all users that is remote to our office.
    My office pfSense allows one of my users to connect to that Windows VPN server flawlessly - but the moment the second user tries to connect it fails. What could be the issue? and where can I look for the issue?

    Here are examples of succesful and failed clients:

    gre 84.85.86.87 <- 192.168.95.19 MULTIPLE:MULTIPLE
    gre 192.168.95.19 -> 50.100.215.44 -> 84.85.86.87 MULTIPLE:MULTIPLE

    tcp 84.85.86.87:1723 <- 192.168.95.19:49416 ESTABLISHED:ESTABLISHED
    tcp 192.168.95.19:49416 -> 50.100.215.44:39081 -> 84.85.86.87:1723 ESTABLISHED:ESTABLISHED
    tcp 84.85.86.87:1723 <- 192.168.95.25:60923 ESTABLISHED:ESTABLISHED
    tcp 192.168.95.25:60923 -> 50.100.215.44:60073 -> 84.85.86.87:1723 ESTABLISHED:ESTABLISHED
    gre 84.85.86.87 <- 192.168.95.25 NO_TRAFFIC:SINGLE
    gre 192.168.95.25 -> 84.85.86.87 SINGLE:NO_TRAFFIC

    Seems like pfSense can't handle multiple "gre"??? I am not seeing this on my other pfSense routers so this is really weired - running version: 2.0

    Thanks,

    Will NOT ever work, protocol limitation. Stop using PPTP, junk and totally insecure.

    It is clearly stated in the documentation and on the pfsense website that you are limited to one connection per remote IP for PPTP.
