Hey folks, I was playing around with the dup functionality discussed here: https://wiki.nftables.org/wiki-nftables/index.php/Duplicating_packets As an experiment, I set up a gre tunnel device (i.e. `ip tunnel add foo mode gre...`) that sent packets to a veth I'd previously set up. I created a rule to dup to this interface and did a tcpdump on the veth to confirm that it worked, which it did. Great. I tried doing the same type of thing, but with a gretap device (i.e. `ip link add foo type gretap`), but this time I didn't capture any packets. Darn. My goal here is to duplicate the whole packet, including the unmodified Ethernet header, encapsulated in GRE. Is this possible with some combination of Linux devices and nft?
