You can specify the size of the encryption key that the Access Gateway requires when it establishes connections. For the Linux Access Gateway, these options are set per reverse proxy (see Section 13.6.1, Configuring TCP Listen Options for Clients). For the NetWare Access Gateway, these options are set globally for all reverse proxies.
In the Administration Console, click > > >
Configure the following fields:
Enforce 128-Bit Encryption between Browser and Access Gateway: When this option is selected, the Access Gateway requires all its server connections with client browsers to use 128-bit encryption. If the encryption key is less than 128, regardless of the cipher suite, the connection is denied.
Enforce 128-Bit Encryption between Access Gateway and Web Server: When this option is selected, the Access Gateway requires all its client connections to Web servers to use 128-bit encryption. If the encryption key is less than 128, regardless of the cipher suite, the connection is denied.
