My campus connections look like this: Dorm1 gateway ----\ Dorm2 gateway ----|=> Campus gateway |-> OUTSIDE Dorm3 gateway ----/ \-> University Servers Dorms' ips are private on different internal networks. I want to allow ssh (and other ports) access on request to users from one of the Dorms to OUTSIDE. If I allow Student1 ssh on dorm1 gateway then what do I tell the Campus gateway to allow ? (I can't allow full access from Dorm1's gateway public ip. I would also like to consider security matters: (allow by ip&mac, or through proxy). Thanks in advance, Bogdan
