Independent mapping, independent filter...

[haryuki]

Hello,

I have the same issues, I allowed JamKazam in my windows firewall app setting,
I have a public IP and I did a port forwarding in my router but I hd the same issue
" Independent Mapping, Independent Filter, random port, no hairpin".

Could you help me?

Thank you

Make you sure that you have a public IP for the first.
You can use the link https://www.showmyipaddress.eu to verify if the Ip which you connect on the web is the number of your physical IP.
If it is not the same, it means that your provider uses a NAT to hide your IP. If is your case, try to call to your Internet provider and ask
if you can a public IP for free or with a subscription. 
The only thing that I don't know and I'm trying to understand is if the users of JamKazam need a static public IP or dynamic public IP
Some providers can allow you to usa a dynamic public IP for free, some only static to subscribe at a cost around $5 per month, almost is so in Italy.
Once you have resolved this problem of public IP as I know you have only to open a port on your router, and for this  you can find a lot of thread about 
under forum "Help with network gear".
I hope my suggestion could be useful for you, I'm in the same situation and I don't know so more than you. I'm writing from Italy and in this moment it could be 
a blessing to jam with other musicians during the "lockdown".
Good Luck.

Thank you for your response ValeRoss


I'm living in France and my provider have to use a NAT to hide my IP because I haven't the same IP in my router
with your link whereas I have a static Ip in my option .

I had the same issues with JamTaba but I resolved it with a full stack option
and to host a server on my machine, I used my Ip coming from my router.
I had no problem.

It will be good if we modify our IP in the network option like JamTaba.

Have a good day

And Take care
