If by "external IP" you mean "WAN IP", then that's not how PPTP works in
this context.  The physical NIC needs a "local" IP in the same subnet as
the modem's "local" IP, and usually both are private network IPs.  This
provides IP connectivity to support the PPTP tunnel, which is then used
for a "virtual dialup" via PPP.  The WAN IP is assigned to the *virtual*
NIC, not the physical NIC.

Some PPTP-capable modems have a built-in DHCP server which can assign the
lower-level IPs automatically.  I'm not sure about the SpeedTouch, but in
any case m0n0wall doesn't appear to support this, so you need to configure
those IPs statically.  The factory default IP for the SpeedTouch is I'm not sure whether the default netmask is /8 or /24, but in
any case (if nothing else is on that physical link) it should be safe to
pick a 10.0.0.x address for the m0n0wall side, where x is something other
than 0, 138, or 255.
