Hi guys, I wanted to ask that in my college, they have implemented something like virtual private network for the lan, in which only the computers connected to a single hub can be seen in network places, for example only two hostels which are connected. rest can be accessed from that hostel through ip address. earlier, we had full access. now how do we send lan messages to one-another. we used to use skype or lantalk xp, but our net connection's limited, so skype's out of question. some otehrs that i used dont showor allow to chat with students of other hostels which do not shre the common hub. so is there any software that would allow us to send messages to each other?
