My Question is that if a Firewall blocks for example a DOS attack of UDP packets. Is it then possible to "break" or take up the capacity of a server by sending enough packets trough a DDOS attack? or does the firewall sort and redirect the packets to a dump where the packets does not take up any processing power?
I asked my teacher and he said that in theory it is possible to "overload" a firewall by sending enough of one type of packet(if we limit ourself to that). But it does not seem like it, at least with a classroom worth of processing power spamming a firewall in one PC.
