Does mt support per-packet load balancing across T1s? I'm currently running a cisco router that load balances 2 T1s for our backhaul. I'm wondering if it is possible to swap it our for a mikrotik, however it must be per-packet and not per-destination load balancing. The best I can find in the MT manual is equal-cost-routing (or something like that), but it only supports per-destination. Any ideas or suggestions would be great!

see "nth" property in firewall manual. you can use it to put one routing mark on the first of each two packets, and another routing mark on the second of them. then use policy routing to reote these packets to different gateways. you should not use source nat in this configuration as this might break things, i think.

I really don't want to use any sort of nat for these backhaul connections, so that sounds great.
