Thanks all. To be clear: I'm dealing with IPIP packets, not GRE packets. Linux LVS emits IPIP encapsulated packets when the target server is non-local. I have no option to emit GRE or another kind of tunnel packet. Also, I'd prefer not to terminate the IPIP tunnel on the firewall. I can, but I'd prefer not to. What I want to do is look inside at the packet encapsulated by IPIP. Even if I have to hand-crank the rules in terms of byte X inside the packet should be value Y.
