Bug Description

Even so netcfg contains code to configure pointopoint links
the relevant dialog box never pops up in the netcfg module.

Once only gets asked for
IP Address
Netmask
Gateway

Sometimes, by going back and forth, one can trigger a dialog
box where all the variables to be filled are listed, this includes
pointopoint, but the relevant dialog seems to be disabled.

Due to this bug network configurations where the gateway is not
within the local (logical) net but only reachable via a pointopoint link
are still not supported.

Example: virtual server on a single IP address:
iface eth0 inet static
        address a.b.c.d
        netmask 255.255.255.255
        gateway e.f.g.h
        pointopoint e.f.g.h

Afterwards the routing would look like:

root@alpha:~# ip route
default via e.f.g.h dev eth0
e.f.g.h dev eth0 proto kernel scope link src a.b.c.d
root@alpha:~# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 e.f.g.h 0.0.0.0 UG 0 0 0 eth0
e.f.g.h 0.0.0.0 255.255.255.255 UH 0 0 0 eth0

Please fix. Thank you.
