Network Setups with EoIP Interfaces

• Possibility to bridge LANs over the Internet
• Possibility to bridge LANs over encrypted tunnels
• Possibility to bridge LANs over 802.11b ‘ad-hoc’ wireless networks

Like PPTP, the EoIP protocol encapsulates Ethernet frames in GRE (IP protocol number 47) packets and transfers them to the remote side of the EoIP tunnel.

Ethernet over IP (EoIP) Tunnelling is a MikroTik RouterOS technique that constructs an Ethernet tunnel between two routers on top of an IP connection based on GRE RFC 1701. The EoIP tunnel can be used in conjunction with an IPIP tunnel, a PPTP tunnel, or any other IP-capable connection.

When the router’s bridging capability is active, all Ethernet traffic (all Ethernet protocols) is bridged as if there were a physical Ethernet interface and cable between the two routers (with bridging enabled). This protocol enables a variety of network schemes.
