Issue<\/strong><\/h2>\n

Traffic is sent out from the ASA unencrypted.<\/p>\n

Cause<\/strong><\/h2>\n

This can be caused by a duplicate (stale) ASP crypto table entry, this prevents the ASA encrypting any traffic destined for the remote host.
There are 2 commands which shows this behaviour. They are,<\/p>\n

Interface outside:
!
out id=0xd616fff0, priority=70, domain=encrypt, deny=false
        hits=855899, user_data=0x473ccf4, cs_id=0xd5deba08, reverse, flags=0x0, protocol=0
        src ip=192.168.100.0, mask=255.255.255.0, port=0
        dst ip=172.16.1.0, mask=255.255.255.0, port=0, dscp=0x0

out id=0xd1592dd0, priority=70, domain=encrypt, deny=false
        hits=0, user_data=0x4bed13c, cs_id=0xd5deba08, reverse, flags=0x0, protocol=0
        src ip=192.168.100.0, mask=255.255.255.0, port=0
        dst ip=172.16.1.0, mask=255.255.255.0, port=0, dscp=0x0<\/pre>\n
Note :<\/strong> Details of this bug can also be viewed within CSCsd48512 (Duplicate ASP crypto table entry causes firewall to not encrypt traffic)<\/em><\/p>\n
Solution<\/strong><\/h2>\n
There are 2 solutions to this issue,<\/p>\n
    \n
  1. Reboot the firewall.<\/li>\n
  2. Upgrade the firewall to a version 7.0(4.13), 7.2(0.46), 7.1(2.1), 7.0(5), 7.2(1) or 8.0(0.1).<\/li>\n<\/ol>\n
