Problems with media port on Jitsi

Hello everybody.

First of all, sorry for my english, it’s not my native language !

So, I’m trying to put in place the jitsi videobridge plugin on my server but, my ISP router sucks. He don’t want to let pass UDP on 50 000 - 60 000.

Yeah ! And I can’t change that.

So, I was trying to change the ports with the new interface (see “ports.jpg” below)

I restarted my server but when I try to go on ofmeet chat message is working as intended but, in no way I can see the other peoples who are outside of my LAN.

When I check my java consol I can read this :

Java console
<candidate

foundation=‘4077555471’

component=‘1’

protocol=‘udp’

priority=‘2122129151’

ip=‘192.168.70.1’

** port=‘57152’**

type=‘host’

generation=‘0’

network=‘1’

id=‘ixyloydthr’/>

I was trying to look on the configurations file but I think this is out of my league ^^

Somebody can tell me how I could fix that ?

Thanks a lot !
