tcp redirect with on the fly modification

[Rajeev Kapoor <raj_kap99 () yahoo com>]

Dear friends,

thanks a lot for replies in "HTTPS redirect tool
thread", here i am with one more request.

i am looking for a tool like Fport, but with the
additional functionality that it should be able to
modify data using rules. 

i could find ITR (interactive tcp relay), but i am
looking a tool where i can predefine the data to be
modified.

For example, i could change maxlen=20 to maxlen=200 on
the fly. The tool should work for all type of traffic,
not just HTTP.

And if I can spice up my wish list, there must be a
way to 
Modify binary data also (may be by specifying ASCII
values)


Is someone aware of such tool/ or is working on tool.

Thanks and regards,
Rajeev
