Very good work, Mike! I cannot believe I overlooked that one setting in L2TP. I wasted two days on that
Just so you know, because I am allowing NetBIOS traffic, I went ahead and assigned my WINS server (specific for this), and did not have to make any adjustments to Address/PTR in DNS.
The only thing I am having problems with, and I'm not sure if there is a fix, aside from changing the iP, is that when I try to access the ZyWall from the tunnel...it keeps trying to go to the device I am connected to for wireless. 192.168.1.1 is very generic, and I know this will be an issue until I can resolve it. For now, I access the ZyWall from the WAN; however I would like to kill that firewall rule at some point to lock it down.
I guess I could always RDP into one of my servers (perhaps make a management hyper-v, and then access it from there??
Thank you for your good work!
