    Hello,

    VprVPN L2TP/IPsec will not connect. For VyprVPN L2TP/IPsec to work, I must allow traffic via ports UDP 500, 4500, 5500 & TCP Port 1701.

    I am running Windows XP Pro 32 bit SP3 with all critical updates installed. I am running ESET Smart Security Version 4.2.71.2.

    If I disable the ESET personal firewall the VprVPN L2TP/IPsec connects immediately.

    I added rules to allow all these ports (one rule for each port). Below is an example of the rule I created for port UDP port 500. I created the same rules for UDP ports 4500 and 5500. I also created a rule for TCP port 1701.

    Example:
    UDP port 500
    Name = VPN
    Direction = Both
    Action = Allow
    Protocol = UDP
    Profile = For every

    Local Tab – Local port = Port:500
    Application = C:\Windows\system32\Lsass.exe (tried both with and without adding this application)

    Remote Tab – Remote port = Port:500 (also tried leaving the remote section blank)


    When trying to connect the log file shows entries for only UDP ports 500 and 4500 as shown below. There are no log file entries for UDP port 5500 or TCP port 1701 even though I created rules for all four ports/


    4/27/2011 6:59:29 AM No usable rule found 0.0.0.0 216.168.2.151:500 255 C:\WINDOWS\system32\lsass.exe NT AUTHORITY\SYSTEM

    4/27/2011 7:04:41 AM Communication allowed by rule 216.168.2.151:4500 0.0.0.0:4500 UDP VPN C:\WINDOWS\system32\lsass.exe NT AUTHORITY\SYSTEM
    4/27/2011 7:04:41 AM Communication allowed by rule 216.168.2.151:4500 192.168.1.101:4500 UDP VPN C:\WINDOWS\system32\lsass.exe NT AUTHORITY\SYSTEM

    What am I doing wrong?
    Thank you, Paul

    Have you tried switching the firewall to learning mode, have the necessary rules created automatically and then switching back either to automatic mode with exceptions or policy-based mode?
