Cisco PIX/ASA VPN client

[S.N.Grigoriev]

Hi list,

I need to use my 7-CURRENT workstation as an IPSec client for
Cisco PIX/ASA devices. I try to use /usr/ports/security/vpnc
for this purpose. But when i start vpnc the following error
message appears:

socket(PF_INET, SOCK_RAW, IPPROTO_ESP): Protocol not supported

Who knows if it is possible to use vpnc with CURRENT? Or may be
I have to use another approach to solve my task? 

Thanks in advance,
Serguey.
