Hi,

RFC 2890 defines how to include a key in the GRE header. The Linux GRE
implementation supports this. But it seems to be quite static.
The key must be specified during tunnel interface creation and apply to
all packets encapsulated via this interface.

How can I have the key dynamically e.g. per packet, per flow or how
ever?

How can a receiving linux box distinguish between different GRE keys?

Ciao,
Dubert
