You can set the MRRU to 65535 if you want. > (PS, I don't recall the details of PPTP.

You can even do (if you desire) a PPtP over OpenVPN to get the added encryption. For what it's worth, it is documented: http://www.mikrotik.com/testdocs/ros/3.0/vpn/pptp.php -- ******************************************************************** * Butch Evans * Professional Network Consultation* * http://www.butchevans.com/ * Network Engineering * * http://www.wispa.org/ * WISPA Board Member * * http://blog.butchevans.com/ * Wired or Wireless Networks * ******************************************************************** -------------------------------------------------------------------------------- WISPA Wants You!
