well

I don't think you can do such thing ...
every tcp connections, uses both directions (every packet you receive you have to send ack).

beside that, routing table uses network ip's to differ one route from another, unless you have specific ip's, you can't divide download and upload throw 2 nics ...

Dear, this is simple you can do this via virtualization, or if you have two systems.

i am defining this using two systems. suppose you have systemA (nic1 isp1, nic2 lan ip=10.10.10.9) and systemB (nic1 isp2, nic2 lan ip=10.10.10.10).

now configure squid on both server, create a squid cache rule on systemA.

cache_peer 10.10.10.10 parent 8080 3130 default no-query


All your web traffic will be forwarded to ISP2 and all Stmp,pop3... will be using ISP1.

using this web is on ISP2 and other traffic on ISP1.

Requirements:-- squid on both, iptables on both systems.
default gateway : SystemA for all nodes on your network.
iptables : to nat other protocols.

thanks.

While I'm not sure how to do it, you can do load balancing on your connection and might help you out. You should be able to tie the NICs together virtually and use it like it's one connection.

hi,

that is an asymmetric routing - but good only if your ISPs support it. This kind of setup typically if you have a DVB-IP connection. You use your dial-up 33600bps analog modem to ISP-A for internet request and use a broadband wireless receiver from ISP-B for the internet reply.

search around.

HTH.
