The GRE code in FBSD/Linux is just a bit of code that handles IP protocol 47 (ie, GRE) and special cases the WCCPv2 decapsulation. > So ip_wccp does not need the GRE tunnel, which is what Henrik said long time > ago ;) > > But removing ip_wccp and having the GRE tunnel does not work for me. > > So for me, using ip_wccp just by itself works fine. Cool. > > What protocol does ip_wccp use? > Does it setup it's own GRE thing? ip_wccp will just register for protocol 47 and decapsulate WCCPv2 GRE frames, feeding them to the kernel for normal processing.
