strange ip route problem

[andy2008]

I have a strange problem on Fedora10.
I have two internet connections so I need to use the "ip route" command to share one of these connections inside a LAN. I created another table in /etc/iproute2/rt_tables and using ip route I added a default via for this table.

Then using iptables with mark and SNAT I share the connection inside the LAN.
Everything went smoothly for about 2 weeks... than all of a sudden my clients start complaining that the internet connection isn't working. So after a few minutes of research I discovered that the default gateway I added for that table I created was GONE.
Does anyone know what the problem is and how could a route disappear just like that?

Well, I solved part of the puzzle. I checked /var/log/messages and noticed that the PPPoE connection had a time out and restarted, thus losing it's default gateway I had added in it's table.

Now, my big question is this: how to make the pppoe connection automatically add the ip route in that specific table if, let's say, something like this happens again.
I did the dumb thing and added the line "ip route add table pppoe default via xx.xx.xx.xx dev ppp0" in the /etc/sysconfig/network-scripts/ifcfg-ppp0 file but of course it did not work.
Does anyone have any thought on this?

setup the static routes you want in /etc/sysconfig/static-routes one route per line. For those routes not associated with a transient interface you prefix the route with "any" so that it is brought up at boot time. All the options of the "route" command are available, but omit the leading hyphen in front of "-net" or "-host".

an example /etc/sysconfig/static-routes :

any net 10.10.10.0 netmask 255.0.0.0 gw 192.168.1.1

I added the route in the static-routes file (I had to create this file cause there isn't such a file in Fedora10).
I removed the MARK from the iptables SNAT
I restarted the network service but it doesn't work.
Users from LAN now download via PPPoE but the upload goes through the linux default gateway, which is the other internet connection... which is exactly what happened before using MARK and creating another table with the ppp default via.

So I must return to my initial question. Is there any way to run this command:
"ip ro add table pppoe default via xx.xx.xx.xx dev ppp0" whenever I or the system restarts the pppoe connection?

I discovered the solution to this problem and because I hate it when people on forums forget to post the solution once they find it, I refuse to be one of those guys.
So, all I had to do was create the file /etc/ppp/ip-up.local, then run the command "chmod 755 ip-up.local"
and add inside this file whatever command I want the pppoe to run after a successful connection.
So I added my ip route command and now everytime I restart the pppoe connection, the route in my pppoe table appears automatically.
