Snapchat messaging not working with iPhone

Hi Iain,

Check #1 in my guide here. If you see any drop reason then you know which configuration part to mangle.

Thanks

Hi, thanks for for the followup.

I ran the drop-packet utility against the IP address in question and it yielded nothing.

No packets dropped.

Hi Iain,

Does you LAN to WAN firewall rule have Decrypt & Scan HTTPS checked? Snapchat will not work if that is the case. Open up the log viewer, go to the web filter portion, and filter by the source ip of the phone. At this point you can open up snapchat and try to view a few stories. You will see a list of URL's that Snapchat is trying to connect to. Look for any the are using https. Copy all of them down and add them in the HTTPS Decryption exception portion under the web module.

Hi... thanks --

Decrypt and Scan is NOT checked. 

I added snapchat.com (per the web filter) to the exceptions and tried again ... and checked Decrypt and Scan... and tried again... still no joy.

Created a WiFi hotspot off my phone and attached the iPhone.. The queued messages went straight out.

I should add, Snapchat messaging works fine from my Samsung phone.

My sister has an Apple phone and will be visiting at the weekend.. Will be interesting to see if it fails on hers too.

Hi Iain,

My apologies. I see were you said it was not enabled in your first post now. Must have been too late for me last night :). Can you post a screenshot of your firewall rule? This is very strange behavior. I had the same issue on our public WiFi at the office and I was able to get it working on all platforms by doing the steps I posted earlier. Not sure why it's not working for you but I will try to help you the best I can.

Sure... I appreciate your help. Been working with firewalls for 20+ years (Checkpoint, Stonegate, PIX etc)... but Sophos is new to me. 

I was new to Sophos last year. It has a little earning curve for sure compared to the others in the marked. I was big into Sonicwall, Watchguard, and PIX/ASA as well. Once you learn XG I think you will like it alot. Anyway back to your issue. The only other thing I see on your rule is IPS. Can you disable that and give it a try?

Hi Iain,

If you do not capture anything in the drop logs than I suspect that the issue is caused due to XG.

Thanks

Tried. No joy!
