System: NetBSD rumolt.teuto.de 1.2D NetBSD 1.2D (RUMOLT) #0: Sun Apr 27 19:36:03 MEST 1997 root@hwart.teuto.de:/usr/src/sys-local/arch/i386/compile/RUMOLT i386


>Description:

Try to map a host from an internal network to its official ip address
on two outgoing interfaces, as in

map ppp0 192.168.112.2/32 -> 194.77.23.162/32
map ipi0 192.168.112.2/32 -> 194.77.23.162/32

The second line fails in the ioctl setting the NAT with "Adress exists".
Not in every setup there is a single "outside".
