-  * some Switches contain a functionality called **//"Hardware NAT"//**; support for this features has not yet been included into OpenWrt. Since the [[docs:techref:hardware:cpu]]s used in CPE Routers are relatively slow, expect 2 to 4 times performance gain if you were to use Hardware NAT, e.g. without hardware NAT some router could achieve 400Mbit/s at full CPU load, with hardware NAT it could achieve 900Mbit/s at full CPU load. OpenWrt developer is supposed to have said, that implementing HW-NAT support would be unacceptably hacky to accomplish.+  * Some switches contain a functionality called **//"Hardware NAT"//**; support for this features has not yet been included into OpenWrt.
