Сannot access to local gitlab server from outside

How to Use GitLab
1

I’m newbie in gitlab, tried to solve problem by myself for some weeks, now looking up for some help

I’v got a centos 7 physical server in local network of 2 computers and static ip

Installed gitlab on centos, forwarded 77 port on router

Since I don’t have a domain, my external_url is IP+port:

external_url 'http://123.456.78.90:77'

Added port in centos in iptables and firewall-cmd:

iptables -I INPUT -p tcp --dport 77 -m state --state NEW -j ACCEPT
firewall-cmd --zone=public --add-port=77/tcp --permanent

From inside the server I can get access to gitlab web interface by address

127.0.0.1:77

There I can see “Clone with HTTP” url in repository:

http://123.456.78.90:77/user/test.git

I go to another outside server and write

git remote add origin http://123.456.78.90:77/user/test.git
git add test.txt
git push origin master

And get

unable to access 'http://123.456.78.90:77/user/test.git/': Recv failure: Connection reset by peer

What did I miss?

Thanks for posting and welcome to the Community Forum, @CloudLegat!

I suspect either:

  • your server is configured to use an internal IP address, not external IP (does the ip start with 192., 172., 10., or 127.?
  • changing the port from default (80) to 77 didn’t work as expected, nginx is still using port 80
  • the port-forwarding rule didn’t successfuly poke a hole in your firewall to allow this system to be public-facing on the internet

A few questions to help troubleshoot:

Are you able to connect to 123.456.78.90 via curl or any other method from outside your Local Network? (tip: try curl -v 123.456.78.90:77 from any machine not on your local network)

If you run netstat -tulpn on the GitLab server, do you see nginx running on port 77 or port 80?

If you run gitlab-ctl tail, and reload the URL http://123.456.78.90:77 from a different machine, do you see any error messages in the logs?

Finally, can you confirm that you’re using an external, not internal IP address. (tip: try curl icanhazip.com on your GitLab server to get the external IP address, verify it matches output in ifconfig or ip a)

Hello, and thank you for answering

My mistake was in forwarding on router to wrong internal port (22)

That’s how it works for me:
external port: 8686
internal port: 77
local ip: 192.168.0.202
protoclos: all
