SIB (Simple IPX Bridge) is able to tunnel IPX and IP frames received by your ethernet device via UDP over the Internet. It keeps track of the path MTU and splits frames if neccesary, can compress the frames via LZO, keep track of local MAC adresses, filter SMB over IPX to reduce traffic, is able to handle custom filters, and is easy to use. It is maintained and tested with 2.2 and 2.4 kernels, and can produce traffic statistics.
