That is likely because tcpdump doesn't see outgoing encrypted packets. So for inbound you see ESP and then decrypted packet - so you see same packet "twice" - for outbound you see packet before tunnel but you don't see packet after it has been encrypted. -- Tuomo Soini <t...@foobar.fi> Foobar Linux services +358 40 5240030 Foobar Oy <https://foobar.fi/> _______________________________________________ Shorewall-users mailing list Shorewall-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/shorewall-users
