MikroTik

We have situation like this:


Internet<->Cisco Catalyst<->Switch<-4xUTP->MT with 5 x rtl8139<-> MT w/Ethernet w/Wireless<-wifi->Network

The problem is that Cisco assigns one DHCP Static IP per MAC address of the eth port.
The card is Realtek quad eth 8139 board.
Each of the eth ports is limited to 2mbit/sek
The problem is to "merge" or "join" the bandwidth from all four eth ports to single "channel" or 8mbit's to the network.
Can this be done by Mikrotik, or can it be done by any software out there.

It is possible in 2.9 version (interface bonding) assuming you have MT routers from both sides of the link.

I don't have MT on both sides.
On one side is Cisco Catalyst Switch, and on the other side is MT with 5 eth cards.
What i need is level3 (ip level) bonding so that i don't desrupt DHCP rules.
If i bond all eth interfaces to bridge, it's level2 bonding and then i have only one mac address from the bridge so i can only have one channel instead of four.

Another alternative would be equal cost multipath routing, but interfaces on MT side should get addresses from separate networks and with different GW addresses.
