Dear Friends,
I switched from useing routed to gated on a FreeBSD 2.0.5. We have a PPP
link over a leased line to our provider. But we only have one real
IP-number, namely 194.10.201.200.
We have a small local Ip-network on ethernet (ed0), using the fake net
192.168.31 and we have three dialin modems for PPP (using ppp for
cleint-ppp) setting up links between:
192.168.32.254 <-> 192.168.32.1
192.168.32.254 <-> 192.168.32.2
192.168.32.254 <-> 192.168.32.2
respectively.
Here is a sample output of netstat -rn:

My gated.conf looks like this:
# Only broadcast RIP information for xxx.xxx.yy out the ed Ethernet interface
#
#
# tracing options
#
traceoptions "/var/tmp/gated.output" replace size 100k files 2 general ;
#
rip yes {
broadcast ;
interface all version 1 ;
traceoptions route ;
} ;
#
#
#
# Turn on a bunch of tracing info for the interface to the kernel:
kernel {
traceoptions remnants request routes info interface ;
} ;
#
# Propagate the route to xxx.xxx.yy out the Ethernet interface via RIP
#
export proto rip {
proto direct {
194.10.201.200 masklen 24 ;
} ;
} ;
#
# Accept routes from RIP via ed Ethernet interfaces
import proto rip interface ed0 tun0 tun1 tun2 {
all ;
} ;
When I used routed, defining some static routes, I could ping from within
the network to outside. This isn't possible anymore. Can someone help us.
We are the system of the Association for Progressive Communication in
Belgium.
Many thans beforehand.
