Fun with EoIP Mike Everest, DuxTel Pty Ltd Ethernet over IP not just another GRE tunnel!
Transparent layer2 transport Presents as a virtual Interface to RouterOS Carries Ethernet frames Can bridge it Can route it Can firewall filter it NAT it Queue it
Bond it Ethernet over IP some limitations! requires routable path (avoid NAT!) proprietary MikroTik (?) watch out for MTU on carrier network
only(!) 65536 unique tunnels Ethernet over IP easy to implement! Router A remote-address (IP of Router B) tunnel-id (0 255) Router B remote-address (IP of Router A) tunnel-id (matches other end) Example 1
Connect to Remote Hotspot Example 1 Internet Gateways Ethernet over IP Hotspots on Layer2 WAN Example 1 HotSpots use pppoe Example 1 Remote/Mobile hotspots connect using pptp
Example 1 Concept: create EoIP tunnel across ppp Example 1 Concept: bridge local wlan to remote HS Remote Router Local Router wlan1 wlan1
