See siscslow_ethernet.c for information about translation between 802.15.4 and 802.3 addresses. Devices must have a proper EUI-64 address for this bridge to work. If the EUI-64 address of the devices cannot be changed and they are incompatible with the translation mechanism, you have to change the translation rules (they are defined in mac_createSicslowpanLongAddr() and mac_createEthernetAddr()).
Usage example:
run tapslip6 (source file are located in tools folder).
./tapslip6 -p 2001:db8:bbbb:abce::/64
where 2001:db8:bbbb:abce:: is the network address and 64 is the the prefix length. The remaining 64 bits will be derived from the EUI-64 (two middle bytes will be removed).
You can also simply create an edge router in one of the network nodes: you have to enable routing and set the appropriate forwarding rules, as shown in contiki-init-net.c. Then you have to add the corresponding rule on your machine, for example:
route -A inet6 add 2001:db8:bbbb:abcd::/64 gw 2001:db8:bbbb:abce:280:e102::8a.
where 2001:db8:bbbb:abce:280:e102::6c is the address of the edge node and 2001:db8:bbbb🔡:/64 is the lowpan address.
