Telkom LTE to Telkom LTE blocked?

[Insaityflea]

Hi All,

I'm running telkom's LTE and some of my friends run it as well.

We were trying to play Arma 3 (using UDP 2302 port) and when a session is hosted on telkom LTE, ADSL users could join but any users on LTE couldn't.

Tested:

- Host on Telkom LTE - Client on Telkom LTE - cannot connect
- Host on Telkom LTE - Client on DSL (various ISP's) - connects and works fine
- Host on DSL - Client on Telkom LTE - connects and works fine
- Telkom LTE to Telkom LTE - Port 443 can communicate to each other. Everything else seems blocked.

Somewhere along the lines telkom LTE to telkom LTE, it looks like certain stuff is blocked? Is it the Hauwei modems that just dont like talking to each other? It's not a ports issue as users on dsl can connect. Also tried a few different ports and still nothing.

Any advice would be appreciated.
Thank you.
