Does TippingPoint devices inspect EoIP traffic?

Summary
A: TippingPoint devices inspect all traffic as long as said traffic is NOT encrypted. By definition, Ethernet Over IP (EoIP) traffic runs in an encrypted tunnel so while the device cannot inspect the traffic it will attempt to do so thus causing additional load on the system.

Note: It is a recommended best practice to utilize inspection bypass rules to bypass encrypted traffic. This is recommended because the device cannot inspect encrypted traffic and attempting to do so can impact performance and cause unnecessary CPU processing load.


General Information:

Ethernet over IP (EoIP) tunneling, is a MikroTik RouterOS protocol that creates an Ethernet tunnel between two routers on top of an IP connection. The EoIP interface appears as an Ethernet interface. When the bridging function of the router is enabled, all Ethernet traffic (all Ethernet protocols) will be bridged just as if there where a physical Ethernet interface and cable between the two routers (with bridging enabled). This protocol makes multiple network schemes possible:

  • 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

Note:  EoIP interface may be configured between two routers that have active IP level connection. The EoIP tunnel may run over an IPIP tunnel, a PPTP 128bit encrypted tunnel, a PPPoE connection, or any other connection that transports IP.
