[Bug 1085712] [NEW] pointopoint link configuration can not be entered

[Michael Neuffer]

Public bug reported:

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 at 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 at 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.
