linux as a gateway

hi chaps, want to rig up a gateway on linux, with like 7 or 8 nics. 1. who knows of problems doing this (pci-wise or otherwise)? 2. who knows of an existant hw-solution ? (needs a large chassis and board and redundant power and so on.) 3. Are there any "embeddeds" with just the nic-ports and little else ? tia dan -- buddha 2.4.20-4GB 1:32pm up 8 days 0:56, 6
