Default decryption failed or bad record mac


Openssl version: 0.9.8a
Objective: secure FTP (SFTP) w/o pasv

Everything works with self signed cert if client that is going to connect is
located ONLY on the same subnet.

If I try to connect a client to the server from outside the subnet, ie.
internet client user, I get a "decryption failed or bad record mac" error.

Scenario:
client (public ip) tries to connect to server (non-route able ip on DMZ with
public IP forwarded). Won't work.
client (non-route able ip on DMZ) tries to connect to server. Does work.

Is there a mechanism inside OpenSSL that doesn't allow cert pass through if
client isn't on the same subnet? Is this a bug?

Please test against 0.9.8h; 0.9.8a is nearly 3 years old at this point.

FIXED

Was a problem with smart defense center altering the packet. Thanks for the
quick reply.
