Port 443

I have deployed MT as Access Point. One customer has complained about not being able to get his streaming on-line stock quotes. I noticed this application uses port 443. Note that I am not using Hotspot on the MT. I noticed that 443 is SSL and is used in hot spot situations. Also, note that my customer authenticates using PPPOE and i do not have any firewall rules so everything should pass. How can I fix?

Add mangle rule.

Can you be more specific? Thank you for your help!

add mangle to set new tcp mss size. refer gto docs.
