Hi,
I have one firewall with 3 ethernet cards, 2 internet links, one cisco
2920 and one problem in RTNETLINK ;o)
Let me explain my network :
| *** Internet Link 1 *** *** Internet Link
2 ***
10.1.0.1| Serial Serial | 10.2.0.1
|||| +--------------+ +------------+
| |
|| +------------+
10.1.0.2| CISCO | 10.2.0.2
+------+-----+
192.168.1.1 / 192.168.2.1
|
eth2 192.168.1.2/ 192.168.2.1
+------------+
FIREWALL
+-+--------+-+
10.20.0.0 eth0| |eth1 10.30.0.0
| |
MY DMZ NET MY CORPORATE NET
I used reserved IPs for security reasons .. <sorry :o( >
What I'm trying to do:
I don't want to use my cisco default route, because I will do some
filtering, based on source address, at my firewall to choose wich link
to use, so I must add (at my firewall) a default route using my ISP 1
end <10.1.0.1> at one routing table, and other default route using my
ISP 2 end <10.2.0.1> at another routing table, and do trafic control
using iptables/iproute <as described in Advanced Routing how-to>.
the problem is ... RTNETLINK says Unreachable Network when I try to add
a route, using a gateway wich isn't directly connected to my firewall
:o( this is the line I'm trying to use :
<I know I'm not writing on a specific routing table to do traffic control>
ip route add default via 10.1.0.1|
RTNETLINK answers: Network is unreachable
So .. I've tried
ip route add default via 10.1.0.1 nexthop via 192.168.1.1
RTNETLINK answers: Invalid argument
Can anyone help me ? If someone need more info, ask me ... <please
reply me at theoc@spread.com.br but I will check this list every day ;o) >

Do you have a route (no default) to that destination? It should work
if you do.

Yes, I can ping 10.1.0.1.
I tried from another box, <one connected to my corporate net> and
without using any default route, I can add a route to 10.1.0.1 using my
firewall as gateway (and my firewall with a route configured too), but I
can't use it as gateway to my default route ... :o/
