I would include the three rules that I showed you earlier. If you want to be more precise, and only allow computer A to print and share files with computer B, but no other computers, then change the rules a little. Rule 1: ALLOW traffic from computer A with destination of computer B and with destination ports of 137:139 Rule 2: ALLOW traffic from computer A with destination of computer B and with destination ports of 445 Rule 3: DENY or REJECT all other traffic from computer A with ANY destination
