hello,
i have configured my SuSE-6.2 linux network (one machine connected to the
internet
via a PPP-modem-connection, another linked to it via ethernet) according
to the description in the
Linux IP Masquerade HOWTO, and masquerading is working fine, when my
PPP-Conection is
up. There is unfortunately one problem when it is down.
on my masqued machine (192.168.0.99) I have the masquing machine
(192.168.0.100) as the default gateway in
/etc/route.conf with
default 192.168.0.100
The problem is that when there is no connection to my ISP, when the
masqued machine
is trying to reach a machine outside my LAN, the program originating the
demand
hangs,
for example, when I ping or telnet an outside machine I do not get an
error message
like "network not reachable" or "host not found" as I do when I remove the
default
gateway with
route del default gw 192.168.0.100
Maybe it is worthwile to mention too that the command
route
which should print the routing table does not answer either when the
default route is
set, and ppp is down.
This may sound like a pseudo problem, but it causes netscape to crash on
the masqued
machine, when there is no connection to the outside. I verified that it
does not
crash when the default route is not set, but does, when the default route
is set, but
the ppp connection is down.
Is there a way to change my configuration in order to have querys to the
internet
return an error immediately on the masqued machine instead of waiting
indefinitely.
thanks in advance for all advice!
Michael
