In particular, your hosts will require ARP in order to pass IP traffic through the switch! 197 - You may pass ICMP packets without limitation, to make debugging easier. 198 - The Trema ''Match'' class has a ''compare()'' method that accepts a ''Match'' argument and may be useful to you — consider the ''!ExactMatch#from()'' method in conjunction. 199 200 '''Extra Credit''' [[BR]] 201 For extra credit (if permitted by your instructor), generate TCP reset segment at the firewall to reset rejected connections.
