Characteristics of a P2P Network - About

Firewalls

• Problem: a firewalled computer can initiate a

connection but not accept connection attempts

from outside

• For a firewalled computer, downloads are not

a problem, but uploads have to be

communicated over a peer.

• For two firewalled computers, it is impossible

to establish a direct connection.
