Hi, this is my first mail to the list, I''m no speak English, but i try my best. this situation attack my attention since i first er about it, but i still don''t have a good solution. There are 2 different networks whit different connection to the internet each one whit their servers (lets call it A and B to each server). it is need to mount some kind of service (webserver for example) in A for internet (lets call it C), but for some kind of external medium (whit external i mean that we don''t have access to it) A is filtered, and none from the Internet can open a connexion whit A. Here is where B appears. A VPN is open between both (form A to B), and then is easy from C to use B, to go throw the vpn tunnel to A. Ok so far, that seems to work, but there is a problem. B has 4 connexion (2in2out) for each interaction between A and C !!!. So the idea is similar, but what we need to do is ones the connexion is initialize (through b) C->B->A is not to use B any more. What thinks about this situation? Could be done? Thanks and sorry again for my poor English. -- ----- Angel Arancibia GNU/Linux User Registered #358969 http://counter.li.org/ ICQ: 327093745 MSN: angel.arancibia@gmail.com ------------------------------- "Computer science is no more about computers than astronomy is about telescopes." - Edsger W.
