From 8bd170750400bfa5e14c3dd2e2d0f305e1ab0e57 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Wed, 10 Oct 2007 15:41:41 -0700 Subject: [IPSEC] esp: Remove NAT-T checksum invalidation for BEET I pointed this out back when this patch was first proposed but it looks like it got lost along the way. The checksum only needs to be ignored for NAT-T in transport mode where we lose the original inner addresses due to NAT. With BEET the inner addresses will be intact so the checksum remains valid.
