I have built tunnels that carry 12000 byte packets. Not sure where this idea comes from. They can be built that will carry as much as 65k bytes. > We use Cipe tunnels to solve that.

Of the tunnels I've done with MT, you just use PPtP and set the MRRU (just like your tunnels). I've done this with standard Linux, too. It is actually quite an elegant solution. -- ******************************************************************** * 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!
