Hello,
Here a set of patches implementing http/tcp set-{dst,src}[-port].
The feature can be useful to connect to a IP/port which is defined in a map.
Regards,

Subject: [PATCH 1/4] MEDIUM: tcp: add 'set-src' to 'tcp-request connection'
The 'set-src' action was not available for tcp actions The action code
has been converted into a function in proto_tcp.c to be used for both
'http-request' and 'tcp-request connection' actions.
Both http and tcp keywords are registered in proto_tcp.c
