BUGS/PROBLEMS + +NOTES + +THANKS + +================================================================================ + +===== +INTRO +===== + +Active port forwarder is a software tool for secure port forwarding. +It uses ssl to increase security of communication between a server and a client. +Originally, it was developed to forward data point to point. However, the need +for bypassing firewalls in order to connect to internally located computers +influenced the further development of the project. + +AF is dedicated for people, who don't have an external ip number and want to +make some services available across the net. + +Moreover, zlib is used to compress the transferred data. + +Using one, permanent data/control channel with flow control / packet buffering +provides good performance and reasonably small latency. + +Multiple clients allow to create more sophisticated tunneling scheme. + +================================================================================ + +=============== +1.

Let's suppose we want to create a http server +on our computer and we are behind a masquerade or a firewall: + +1) We have to find some machine on the net with an external ip and a shell + account. + +2) Use "make" to compile everything on that machine. (you can freely remove the + afclient and client.rsa files) + +3) You can edit the config file or just type from the console (to use the config + type -f <cfgfile>) : + $ ./afserver + This will work, if you want to use default values: + - hostname will be taken from hostname function (it would be ideally, if + there is appropriate registration in /etc/hosts) + - server will be listening for users on port 50127 + - server will be listening for client on port 50126 + - server will be for maximum 5 users + - server will forward tcp packets + - there will be no logging and no verbose messages + - there will be no password identification + - ip protocol family will be unspecified + +4) We use "make" on our machine (we can delete everything apart from afclient + and client.rsa) + +5) We are typing from the console: + $ ./afclient -n <name of the server> -p 80 + Where <name of the server> is a string like : 'bastion.univ.gda.pl' or + '153.19.7.200' + +6) We can now enter with a web-browser to: <name of the server>:50127 and we + will enter to our computer in the fact. + + 5.2 reverse udp mode + -------------------- + + local network |FireWall| Internet + || (udp) + || User 1-------AF Client + || /(tcp) + AF Client <---Encrypted/Compressed channel---> AF Server + / || | + /(udp) || (tcp)| + / || / + Game server || AF Client-------User 2 + || (udp) + + +Let's see how to use af to forward udp packets.
