hi all, i want guidance in advance routing--to be specific load balance between two links.. i have gone thru the LARTC docs and docs for julians patches too.. am yet to implement it but have a few queries/doubts.. our setup--> we have two providers. the present one is thru a wan link using cisco router & the 2nd is a wireless link terminated in another router. these two routers will be connected to linux box(its a compulsion to have 2 routers).. the linx box has 3 interface, 2 of wich are connected to the router via a switch.. we already have valid/real ip with us after going thru the docs i find that with julians patch one needs to **MASQUERADE** to the links... we dont want that !.. we want our real ip to flow in these 2 links(real ip already being broadcasted on provider's network).. so my Question is-->possible without **MASQUERADE** ??.. will the setup(as shown in docs) loadbalance for our real ip's ?? .. what other things i have to consider ?.. Awaiting a reply very very anxiously.. A.H

Not without the Linux router performing NAT. > what other things i have to consider ?.. I would consider doing some NAT in one way or another. In my case I perform two consecutive rounds of NAT, one in each router, and again in the Linux router. In short, in order for Julian's patches to work and to load balance the connections, the Linux router must be doing NAT. So I would look into a topology in your network that would allow for the Linux router to perform NAT. Otherwise I do not believe you will be able to load balance your connections. -- Sincerely, William L.

Of course, it is possible ... and depends on how restrictive are your providers. But if one link fails you can have the problem of using sources for the failed link, then the replies from world will hit the failed provider and will not reach you. As result, your internal servers should know which source addresses to use according to the link state. The masquerade simply guarantees that one link is used only from addresses that are reachable from this link. > what other things i have to consider ?.. As for applying the patches you need to download them correctly. More likely you have white space problem (try with patch -l). > Awaiting a reply very very anxiously.. > A.H Regards -- Julian Anastasov <ja@ssi.bg>
