"Communications with the AIM proxy timed out. Try Again." Is the error that my friend and I get when I try to send him a pic or a file via iChat. He is the ONLY user i've ever had this happen with. He has a macbook, I have a powerbook. He has a Linksys WRT54G, I have a WRT54GS We are both on 10.5.2 We are both DMZ in our routers. We are both using LittleSnitch on our systems, but any connection is allowed forever in iChat in the LittleSnitch setup. We both have the apple firewall disabled. The strange thing is that I can use ARD and connect to and observe or control his computer, but i can't even send a file via ARD's drag and drop file xfer feature. I don't get this at all. He claims that when he first got his MacBook he was able to send and receive pics and files with others on his buddy list, but now he can't. He has never been able to w/ me from day one. Does anyone have any suggestions on what I could try? Thanks!
