[44net] Making Gateways With Home Routers ?

Hi there I saw that Microtik Routers support IPIP by default Is it possible to make a gateway with home routers ? If yes how to deal with 300 tunnels lines to the rest of the gateways on the net ? will a home router have enough memory for that ? 2) I saw that OpenWrt also support IPIP so what about doing Gateway with home Router (my TP-link 741ND router is one of the routers that support OpenWrt) will it work ? (before I flash it ) or is there any limitation ? Please Advice Thanks Forward Ronen - 4Z4ZQ http://www.ronen.org
