If he needs a non-nat IP, then he has to be "on" the same network as his gateway. I've done this in the past with a PPtP tunnel, which may be a solution. Another possibility, if he has an MT router, would be EoIP to get him "to" the public network directly. You could do a vlan as well, assuming his gear will support it. There are a number of ways to make that work, depending on the network layout. -- ******************************************************************** * Butch Evans * Professional Network Consultation * * http://www.butchevans.com/ * Network Engineering * * http://store.wispgear.net/ * Wired or Wireless Networks * * http://blog.butchevans.com/ * ImageStream, Mikrotik and MORE! * * NOTE THE NEW PHONE NUMBER: 702-537-0979 * ******************************************************************** _______________________________________________ Mikrotik mailing list [email protected] http://www.butchevans.com/mailman/listinfo/mikrotik Visit http://blog.butchevans.com/ for tutorials related to Mikrotik RouterOS
