LVS, director and SSL cipher

Some odd behavior, handshake with a specific cipher passed with the director but not when handshake directly with a realserver.

openssl s_client -connect VIP:443 -cipher EDH-RSA-DES-CBC-SHA
openssl s_client -connect VIP:443 -cipher DES
=> Connected

openssl s_client -connect RIP:443 -cipher EDH-RSA-DES-CBC-SHA
openssl s_client -connect RIP:443 -cipher DES
=> No connection

Asus Router – Port Forwarding

Caused me some grief for its lack of notification in the UI. I enabled uPnP on the IP camera and it showed up in the port forwarding log but it could not be accessed. Port is open. It turned out that I need to also explicitly enable Port Forwarding (and leave the it other settings empty). It’s good for security but at least it should have a log to show why it’s not working properly.
