Hi.

I have been researching TCP/IP yet have little experience with these
protocols.

I am aware that a firewall (amongst other things) filters the
datagrams being sent/received to/from sources/destinations.

If I have an internet connection at work that allows me to
Request/Respond within web pages why is it not possible for me to
create my own listner in C++ that will allow my pc at work to receive
requests from my pc at home.

ie how do I get around the firewall?
I also have the same problem if I try to create an application that
downloads webpages at work. ie it prevents the application from
downloading as it has not logged onto the firewall.

I would like to share my work to and from work in an easier fashion.
Currently I have a webserver at home that allows file transfers etc
but its not the level of communication which I am satisfied with.


Thanks

You had best talk to your IT department at your work place and
get them to set you up. Trying to go around their firewall with
out their permission may result in your termination (and they are
hip to these things).

Plus a bit more. Firewalls filter on protocols and port numbers within
TCP e.g. HTTP port - 80 etc

Rules on corporate firewalls (e.g. Checkpoint) are unidirectional.
Whilst there may be a rule which allows http out it may not let it in.

You talk to your corporate security/IT dept - trying to circumvent
your corporate firewall is not good for promotion prospects!

I can say this, I am an assistant network analyst where I work. We did
catch a user trying to circumvent the firewall, he lost his computer
privs.. not to mention I think he was fired a few days later.

Don't remember though.
