Single NIC for Wan Multiple for LAN

[cntlr001]

Hello,
I have an older DELL power edge 2800. Currently we have 2 NIC's one for the WAN one for the LAN. I wish to increase my users access speed. Can I team and or bond up to Four NIC's on the LAN side and leave the single NIC for the WAN? I am having trouble finding any info on the net for pulling this off. I have 67 users and throughput is getting a little rough.

The feature is called a number of things since many manufactures did it their own way before the standard was adopted. In general its called LACP ie 802.1ad.
Both the server and the switch need to have this feature...or a proprietary variant that is compatible.
