Running Remote User PPTP
When first starting the remote host (before connecting to the ISP or to the Firebox),
the user may be prompted for a name, password, and possibly even a domain. These
values are what Windows assumes the remote host uses to connect to the network
behind the Firebox. However, if Windows finds a discrepancy, it displays a login
prompt for the network with the name, password, and domain that would be used if
the remote host were at an office connecting directly to the LAN.
Configuring debugging options
WatchGuard offers a selection of debugging options that you can set to gather
information and help with future troubleshooting.
For information on how to enable logging for IPSec, see “Debugging Mobile User
VPN” on page 140. For information on how to enable logging for PPTP, see
“Debugging Remote User VPN (PPTP)” on page 140.
Remote User PPTP is usually set up such that the remote machines use
nonpublic IP addresses from the range used behind a Firebox. If the “Use
Default Gateway on Remote Network” parameter is enabled, and you try to
browse the Internet during a Remote User PPTP session, the Firebox
transmits the private address as the source IP address in the packet
header. Because the remote host was assigned an address from a private
address pool, a public Web site will not know how to route the return
traffic, and will ignore your request. Therefore, browse the Internet before
or after you are connected to the Firebox, but not during a Remote User
PPTP session.
If simultaneous access to the Internet and a private network is required,
contact WatchGuard Support for alternative solutions.
