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) >
