A basic doubt,Many places i have read,if a packet is fragmented to a tiny packet,
routers and many firewalls allow to pass through.My doubt is if the router or firewall
recievs a packet ,from that if it could not make out where this packet is going ,it
should drop by acess-lists or rule base.As when we configure a access-list ,it means
only packets configured to pass are only allowed.similarly in firewalls ,by default
all traffic comming to inside network is dropped.then how could a fragmented packet
traverse? what is the difference between a big packet and a fragmented tiny
packet?Also i learned somewhere ,routers and firewall virtually reassemble the packet.
thanks
mohamed.
