Inline SSL L3 Tool NAT or PAT Support


HTTP/1.1 over TLS

The HTTP request in HTTP/1.1 has an option to include a cookie field in its header. The GS passes client hello SNI from client side GS to server side GS by inserting a cookie in the HTTP request packet before sending to inline tool. Server side GS will use the SNI in the cookie field to start SSL connection to server.

GET /sample_page.html HTTP/1.1

User-agent: Wge/1.12

Connection: Keep-Alive






■   Decrypted data to inline tool is limited to HTTP/1.1 protocol over TLS, inline tool will only see encrypted data on other application protocols.
■   The StartTLS traffic will not be decrypted as it is non HTTP traffic.
■   It does not support bypass tool since all the packets from client or server need to pass to inline tool for NAT or PAT.
■   This feature will not co-exist with features such as Network group multiple entries, Inline network high availability, RIA, Tool early engage, one-arm, and Destination port translation.
■   IPv6 is not supported.
