Hi, can anyone help me with this problem i've got!

I have a problem with routing on my Mandrake 7.2 Linux Box i was wondering if you could help me with.  I live 

in Australia and as broadband access isn't very available at the moment, i have 2 modems to dialup to my isp 

(dynamic ips assigned) to increase my bandwidth at an affordable level.  What currently happens is i have a 

LAN which accesses the internet through my Box that has IP Masquerading set up on it.  My problem is whne i 

dial in with both connections, it only routes the internet through the last ppp connection i've made (usually 

ppp1). This means that although ppp0 and ppp1 are connected to the internet, my computers on the LAN (ip 

192.168.1.x) are only connecting through one modem.  What I need is to know how to set up routing, or 

Loadsharing so that i can utilise both modems over my Masqed network.

What happens when i type route -n in the command line:

Destination Gateway  Genmask  Flags Metric Ref Use Iface
198.142.149.254 0.0.0.0  255.255.255.255 UH 0 0 0 ppp0
198.142.150.254 0.0.0.0  255.255.255.255 UH 0 0 0 ppp1
192.168.0.0 0.0.0.0  255.255.255.0 U 0 0 0 eth0
127.0.0.0 0.0.0.0  255.0.0.0 U 0 0 0 lol
0.0.0.0  198.142.150.254 0.0.0.0  UG 0 0 0 ppp1


My Desired Set Up:

Internet  Internet

   |              |
   |ppp0       |ppp1
