Hi guys. I'm trying to enable of Traffic Flow Confidentiality (TFC) in stro=
ngswan, which should be supported by looking in man:

http://www.manualpages.de/FreeBSD/FreeBSD-ports-9.0-RELEASE/man5/ipsec.conf=
.5.html

Section 2.7 in the following URL describes the implementation of Traffic Fl=
ow Confidentiality (TFC) Padding.

https://tools.ietf.org/html/rfc4303#page-17

Can one of you guys tell me if this is supported in freebsd, because when I=
 try to use it for strongswan I get following message:

ESP_TFC_PADDING_NOT_SUPPORTED, not using ESPv3 TFC padding

Best regards
Lars Pedersen
