Could not Trickle ICE server using external IP

[AmitKasundra]

Hello, I have setup Coturn server from Url https://www.webrtc-experiment.com/docs/TURN-server-installation-guide.html#coturn in Ubuntu.

Turnserver is working fine using local-ip, but when I try to trickle using exernal-ip I get error Not reachable?

If I access turnserver from browser url I can access it using external-ip. I get message.

TURN Server
https admin connection

To use the HTTPS admin connection, you have to set the database table admin_user with the admin user accounts.

My turnserver.conf looks like:

user=test:test123
listening-port=3478
tls-listening-port=5349
listening-ip=192.168.22.101
relay-ip=192.168.22.101
external-ip=202.137.12.10
realm=yourdomain.com
server-name=yourdomain.com
lt-cred-mech
userdb=/etc/turnuserdb.conf

cert=/etc/ssl/my-certificate.pem
pkey=/etc/ssl/my-private.key
no-stdout-log

My turnuserdb.conf looks like:

test:test123

I am starting turn server using command:

sudo turnserver -a

And I try to trickle using below format:

turn:202.137.12.10:3478[test:test123]

Trickle: https://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/

Please tell me where I am going wrong.

maybe it will helps, but problem likes we've got
in our situation we use router IP address and it start's to work, you could try something like this

external-ip=202.137.12.10/192.168.22.1 (your router ip if exists)

[AmitKasundra]

Hi mvsvolkov, I got what was going wrong, it turned out to be that UDP port 3478 was blocked.

Also I was able to get trickle if I used

turn:202.137.12.10:3478?transport=tcp[test:test123].

My external-ip looks like

external-ip=202.137.12.10 (public ip) /192.168.22.101 (local-ip)

I have the same problem, I tried your way but did not work. Can you help me fix it?

listening-device=chanhbc
relay-device=chanhbc
listening-ip=192.168.1.109
listening-port=3478

Try to remove ALL of these options:

• listening-device=chanhbc
• relay-device=chanhbc
• relay-threads=50
• userdb=/etc/turnuserdb.conf # THIS IS NOT an SQLITE db I guess!!
• mobility
• stale-nonce

Please tell me where I am going wrong. Sorry for my English not good.

[chanhbc]

thank @misi i try but it not working

[MazenImara]

you have to configure you router port forwarding and add port map with port 3478 and your local ip

[chanhbc]

thank @MazenImara, i install success on Server not on My Computer

[neo125874]

@chanhbc Hi, could you share how you solve this problem?

[chanhbc]

i config after run my server ubuntu and it's working.

[neo125874]

@chanhbc what king of config? could you explain more? thanks!

[chanhbc]

I will answer you tomorrow, because I do not remember my turnserver configuration

[neo125874]

@chanhbc many many thanks, hope to see the setting tomorrow, we ran into this situation recently...

[chanhbc]

This project I did many months ago so I will try to answer if I remember.

I followed the instructions here: https://www.webrtc-experiment.com/docs/TURN-server-installation-guide.html#coturn
My configuration file:

listening-port=3478
tls-listening-port=5349

listening-ip=my-server-ip
relay-ip=my-server-ip
external-ip=my-server-ip

realm=coturn-ubuntu
server-name=my-server-ip:7812

lt-cred-mech
user=username:password

#cert=/etc/turn_server_cert.pem
#pkey=/etc/turn_server_pkey.pem

no-stdout-log

Results when I test in ICE trickle,

[neo125874]

@chanhbc hi, you mentioned above "server-ip", public or private? and you built the server then the mobile or broswer are in different wifi?

[chanhbc]

That is the public ip (ip can access server control from another place) is usually the IP-WIFI of the server

[chanhbc]

When you install turnserver on the server, it is accessible anywhere as long as there is a network (I have not tried it with ip6)

[neo125874]

@chanhbc did you have your server behind firewall? any further configuration?

[chanhbc]

No, I do not have to configure the firewall on my server. I recommend running on a trial server (I can not install on google server)

[neo125874]

@chanhbc thanks for sharing, our issue happened cause of the firewall, but really appreciate for your config & testing pics.

[RamyaAshika]

Have you fixed it @neo125874 I'm also facing same problem

Perhaps this can help you:

• Check your firewal for allowing TCP/UDP over your TURN server PORT
