Is there any relaible way of doing this? I have 3NIC cards, 192.168.1.45 intranet and two separated DSL line with separate static IP addresses but with local 192.168.10.5 and 20.5. both go to their reouters 10.1 and 20.1, local NIC does not have a default gateway at all. both DSL NICs have their routers default gateways. I have applied RIP service on the XP as well as I have added both internet NICs to the routing table: route add 192.168.10.5 192.168.10.1 route add 192.168.20.5 192.168.20.1 but still time to time a default gateway from one of "random" NIC cards dissapear just to show up again after couple minutes. This is not reliable netwok. Does anyone have any thoughts or solution for multiple NIC cards (min. 3) in one XP where each NIS needs its own default gateway?? Maybe some software solution.. I dont know. Please help!

Two DSL connections on one PC with no connection management software sounds like a huge headache. You have multiple gateways and occassionally a nic see's the other. If you can sniff the network traffic you could probably get a better picture of what is happening, but why not simply get a router that can handle two WAN ports?

because I may want to add more WANs in the future, let's say: 5 more. In addition, even if there is only one DSL, there are two NICs and local one gets confused where to send traffic

I did; like I wrote I have addedd routings for both internet NICs to route its traffic to their own difault gateways, still default gatewa drops. so bizzare that such a simple thing is hard to achieve. traffic coming from certain eth card should come back to it, not to any other card. I understand.. win 95, even xp, but not xp pro sp2 or even 2003 server....

Windows simply isn't built for this purpose and it will have issues. If you decide to 10000 DSL connections your best bet from a reliability perspective is to get hardware than can adequately manage multiple drops. Whatever number you use is irrelevent, getting hardware to decently manage it would be. Of course it's not required as you've discovered but certainly more stable. Just an opinion...
