Yes but I need to have the whole stuff under one or two public IP
(where it shouldn't matter through what modem the data comes in or
goes out) and I believe this would require to cheat with the MAC addresses.
Imagine something like the following
-------------------
------- | PC (NAT Gateway)|-------modem1
| Hub |---| two public IPs |-------modem2
------- -------------------
(could also use a hub and only one NIC then, for sure, whatever would
work)
If a packet for IP1 comes in, and modem1 is pretty much loaded, I'd
like to send the answer back over modem2 and viceversa.

I can get static (which I would) but at the moment, I got DHCP.
Defaultroute is always the same but dependant on what

I could either do this (easier, as three NICs in one machine sometimes
case a bit of a headache or the above mentioned)
