Description (partial)

When incoming ESP packet has as final destination a local interface on the GM itself (including loopback), the packet is recirculated after decryption causing it to be dropped. If the decrypted packet is only a transit one, for example, it is for a host on a connected LAN, all works as expected.

This issue occurs due to getvpn, ipv6 and use of ingress ipv6 access lists.
