# THIS EXAMPLE IS WRITTEN FOR IP FILTER 3.3
|

|
#
|

|
|
# ppp0 - (external) PPP connection to ISP, address a.b.c.d/32
|
||
|
|
#
|
||
|
|
# ed0 - (internal) network interface, address w.x.y.z/32
|
||
|
|
#
|
||
|
|
# If we have only 1 valid IP address from our ISP, then we do this:
|
||
|
|
#
|
||
|
|
map ppp0 w.x.y.z/24 -> a.b.c.d/32 portmap tcp/udp 40000:60000
|
||
|
|
map ppp0 w.x.y.z/24 -> a.b.c.d/32
|
||
|
|
#
|
||
|
|
# if we get a different dialup IP address each time, then we would use:
|
||
|
|
#
|
||
|
|
#map ppp0 w.x.y.z/24 -> 0/32 portmap tcp/udp 40000:60000
|
||
|
|
#map ppp0 w.x.y.z/24 -> 0/32
|
||
|
|
#
|
||
|
|
# If we have a class C address space of valid IP#'s from our ISP, then we can
|
||
|
|
# do this:
|
||
|
|
#
|
||
|
|
#map ppp0 w.x.y.z/24 -> a.b.c.d/24 portmap tcp/udp 40000:60000
|
||
|
|
#map ppp0 w.x.y.z/24 -> a.b.c.d/24
|
||
|
|
#
|
||
|
|
# or, if we only have a small number of PC's, this:
|
||
|
|
#
|
||
|
|
#map ppp0 w.x.y.v/32 -> a.b.c.E/32 portmap tcp/udp 40000:60000

#map ppp0 w.x.y.v/32 -> a.b.c.E/32
|

|
|
#map ppp0 w.x.y.u/32 -> a.b.c.F/32 portmap tcp/udp 40000:60000
|
||
|
|
#map ppp0 w.x.y.u/32 -> a.b.c.F/32
|
||
|
|
#map ppp0 w.x.y.t/32 -> a.b.c.G/32 portmap tcp/udp 40000:60000
|
||
|
|
#map ppp0 w.x.y.t/32 -> a.b.c.G/32
|
||
|
|
#map ppp0 w.x.y.s/32 -> a.b.c.H/32 portmap tcp/udp 40000:60000
|

#map ppp0 w.x.y.s/32 -> a.b.c.H/32
|

|
#map ppp0 w.x.y.r/32 -> a.b.c.I/32 portmap tcp/udp 40000:60000
|

#map ppp0 w.x.y.r/32 -> a.b.c.I/32
