Firewall settings for TCP and UDP are both set to Enpoint Indpendent.
IPsec is on.
I have setup a DHCP reservation for my work laptop and included the same IP in the DMZ (the IP as defined by the router - 192.168.0.9).  I attempted a wired login to my work VPN network with the same results.  The logon script was found but errored out after 10 attempts.  I pulled the LAN cable out and attempted via wireless.  Same issue as before.
At this time, I jumped back on the router interface to check the logs.  While looking at other stats, I noticed that two IP addresses were now assigned to the work laptop (guessing the "new" IP was because I went wireless?).  I then added a second DHCP reservation for the second IP for this machine, 192.168.0.7.
I rebooted the laptop and attempted to login wired.  It failed as before.  As soon as the logon script went through it's 10 iterations and then failed, I unplugged the LAN cable for 10-15 seconds and then plugged it back in.
Lo and behold - the logon script finished logging in...successfully.
That's the good news.  The bad news is that I have to unplug and then re-attach the LAN cable after a failed login before it will work wired.  Still no luck with wireless.
Any thoughts?
