Currently, only the encapsulated part of the packet is logged, e.g.
Eth IP1 GRE IP2 TCP Payload
gets logged as
Eth IP2 TCP Payload
and
Eth IP1 IP2 TCP Payload
gets logged as
Eth IP2 TCP Payload
Note:
Decoding of PPTP, which utilizes GRE and PPP, is not currently supported on architectures that require word alignment such as SPARC.
