When I select an attachment to send via my Gmail account everything looks fine until I click on “Send”. It then sits there until I stop the “Send” process, I’ve left it for 10-15 minutes.

What do I need to do to allow Gmail attachments to work correctly through my router?


Problem caused by dropping non-http connections on port 80 due to firewall setting.

Disable this to get it going.
Firewall >> General Setup  “Drop non-http connection on TCP port 80”
