hello,

I set up gated so it announces and installs network routes for my
dialup-IP networks to the loopback interface as reject routes, so
that packets for not-currently-connected customers generate an ICMP
'no route' message.

pinging an address in that networks from the local machine shows the
expected result -- 'ping: sendto: Network is unreachable'. pinging
from any other source just gives nothing -- tcpdump shows no response
either. 


the routing table looks good to me:

xxx.yyy.5         127.0.0.1           UR          0      577  lo0
xxx.yyy.5.153     xxx.yyy.13.3        UGH         0     1141  ef0

...and the gated.conf too:

interfaces {
        interface lo0 reject ;
} ;

static {
        default gateway xxx.yyy.13.1 retain ;

        xxx.yyy.5.0 interface lo0 reject ;
}


so where's the error?

thanks in advance,

cm.
