I am wanting to connect multiple internet connections (T3,Cable Modem,DSL) each direcly connected to the switch and do load balancing between them. Of course each interface on the switch will have IP blocks setup and I need to NAT them.

Before I buy a Cisco Layer 3 switch (3750,3550) I want to make sure it can do this and if someone can point me in the write direction on doing it.

Hi Friend,

3750 and 3550 does not support NAT. Your loadbalancing is still possible on these switches but Natting is not posible.

Thank You

I was thinking if it was a layer 3 switch it will do NAT but I guess not

What you you recommend for what I am trying to do?

Hi Friend,

I believe router with respective interface or if budget is not a concern than 6500 switch.
