Mapping proxy inbound to outbound connections

[Jon Snow <js...@gatesec.net>]

Hi,

I want to tie together the inbound and outbound connections for a forward or 
reverse proxy session. I figured I would add the source ports to the log 
which would enable me to track the connections through firewall logs etc. 
based on addressing/port combinations. I was looking at writing a module/
filter to do this. Would this be possible and the best way to go or would 
there be an easier way?

Thanks,
Jon
