SSL Handshake ：Bad Record Mac

case 1：

SSL3_GET_RECORD:decryption failed or bad record mac

I am using wpa_supplicant 0.4.8 on Windows XP. With the exactly the same
configuration, on some computers the TTLS/MSCHAPV2
consistently fails with error "SSL3_GET_RECORD:decryption failed or bad
record mac". With other computers, I get success consistently.

I have searched over the internet. It seems the problem is with OpenSSL
library. The OpenSSL version I am using is openssl-0.9.7d. I am
wondering if anyone knows about any fix or workaround for this problem.

case 2：

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.

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