Strange issue that just started happening about three days ago. iPhones that are connected to the wireless (I have a WRT54G running dd-wrt connected to the UTM- NOT using the WAN port) are unable to receive iMessages with pictures. This was working previously with no issues and I made no changes other than allowing automatic pattern updates.
The problem seems to be with the web filtering- which I determined by turning off security modules one at a time until the messages began working again.
I am currently running the proxy in transparent mode. I saw that this was an issue that came up before in the forums, but the "solution" then seemed to be geared towards application control issues rather than web filtering and didn't seem to work for me when I tried it anyway.
I don't have access to the log data at this very moment, but I can add that on when I do. While I was watching the live log, I was seeing status 200 messages, so there was nothing obvious about a block.
I just wanted to see if anyone else was running into this as well. I'll post log data when I can update this post later.
EDIT: I am running firmware version: 9.102-8 and pattern version: 47843
