How do I configure my router to use iChat?
You must open ports on your router to allow incoming traffic while using iChat. iChat uses the following ports: • 5060 (UDP) • 5190 (TCP) File Sharing • 16384-16403 (UDP) To video conference with other clients If you are using the Mac OS X Firewall, you may need to temporarily turn off the firewall in the Sharing preference pane on both computers. To use the Mac OS X Firewall, you must open the same ports as in the router: Step 1 Choose Apple menu > System Preferences. Step 2 Choose View > Sharing. Step 3 Click the Firewall tab. Step 4 Click New. Step 5 Choose Other from the Port Name pop-up menu. Step 6 In the Port Number, Range or Series field, type in: 5060, 16384-16403. Step 7 In the Description field type in: iChat AV Step 8 Click OK. Read here for file sharing configuration if using Mac OS X Firewall.
