I have a VPN where I can log in using PPTP or L2TP.
I can log in with PPTP with no problem, however, I cannot login with L2TP.
If I disable DW protection, both inbound and outbound, I can connect using L2TP, however, if I only disable the inbound or the outbound I cannot connect.
I am not getting any warnings from DW3 when this occurs and the VPN is trusted in DW3.
When I attempt to log in, the DW3 log indicates lsass.exe "Attempt of connect to the UDP port 500"
I apparently need to allow this port, however, I'm not sure how I do it or if it is safe to do so.
NOTE: Port 500/UDP is used for ipsec Internet Key Exchange.
