Default Network route problem

Hi,

I have the following problem.

Here is the output of : route -n :

0.0.0.0 192.168.50.2 0.0.0.0 UG 0
0 0 eth0
169.254.0.0 0.0.0.0 255.255.0.0 U 1002
0 0 eth0
172.16.2.6 192.168.50.184 255.255.255.255 UGH 0
0 0 eth0
192.168.50.0 0.0.0.0 255.255.255.0 U 0
0 0 eth0



When I try to ping 172.16.2.6, it doesn't work while the first available
route is used (0.0.0.0 via 192.168.50.2)


How can I modify the order of the route table to force use of the right
route ?



Thanks for any help

What is 192.168.50.184? From the routing table, its the same ethernet nic so it's no wonder the route to 172.16.2.6 is using the
0.0.0.0 (default) route (even though it looks like you've tried to force it to a different route). If you want to split the
192.168.50 network you'll need two nics, you'll need to set the netmask correctly to split it between them, then you will be able to
set the 172.16.2.6 host to route a different way.

So the 50.184 address is another box which you have an ipsec tunnel to from the machine that this network route is on? How are you
creating the tunnel?

And please don't top post, it makes it hard to consistently read the thread.

Default Network route problem

Yes, 50.184 is another box on the network on which the tunnel has been
setup via racoon.
On 50.184 the access to 172.16.2.6 works fine. ANd I want to use 50.184
as a gateway for this host on the network.


What email address have I to use to do not top post ?

Do you have ip forwarding turned on on the host that you are trying to route over the tunnel (the one with the 172.16.2.6 route)?
And not top-posting (or bottom posting) is simply done by posting your replies at the bottom of the thread, not the top. That way
people can read from top-to-bottom of a thread (like a book). Makes the threads much easier to follow then top posting (the
Microsoft Outlook default).

Yes the ip forwarding is enabled.
With the route table I've described, I am directed on 50.2 and If I
place on it the route to 172.16.2.6 via gw 50.184 it works.

But I consider that It is not necessary to pass via 50.2
It is why I search a way to modify the routage table

Can you show a "traceroute 172.16.2.6" when you've got the tunnel up?

What is 192.168.50.184? From the routing table, its the same ethernet nic so it's no wonder the route to 172.16.2.6 is using the
0.0.0.0 (default) route (even though it looks like you've tried to force it to a different route). If you want to split the
192.168.50 network you'll need two nics, you'll need to set the netmask correctly to split it between them, then you will be
able to
set the 172.16.2.6 host to route a different way.

So the 50.184 address is another box which you have an ipsec tunnel to from the machine that this network route is on? How are you
creating the tunnel?

And please don't top post, it makes it hard to consistently read the thread.

Kevin

Do you have ip forwarding turned on on the host that you are trying to route over the tunnel (the one with the 172.16.2.6 route)?
And not top-posting (or bottom posting) is simply done by posting your replies at the bottom of the thread, not the top. That way
people can read from top-to-bottom of a thread (like a book). Makes the threads much easier to follow then top posting (the
Microsoft Outlook default).

Kevin

Yes the ip forwarding is enabled.
With the route table I've described, I am directed on 50.2 and If I place on it the route to 172.16.2.6 via gw 50.184 it works.
But I consider that It is not necessary to pass via 50.2
It is why I search a way to modify the routage table

Can you show a "traceroute 172.16.2.6" when you've got the tunnel up?

Kevin


traceroute to 172.16.2.6 (172.16.2.6), 30 hops max, 60 byte packets
1 192.168.50.2 (192.168.50.2) 0.187 ms 0.166 ms 0.154 ms
2 192.168.50.184 (192.168.50.184) 0.545 ms 0.600 ms 0.603 ms
3 * * *
4 172.16.2.6 (172.16.2.6) 5.958 ms 4.324 ms 4.390 ms

It should use directly 50.184 and not first 50.2
