pain with setting base url when needed access from outside by public ip and inside network by internal ip

[NikolayUvarov]

Description

1. when starting configuration server listens localhost and not 0.0.0.0 as stating in its log, so
   2022/08/31 10:29:54 cmd/web.go:217:listen() [I] [630f0df2] Listen: http://0.0.0.0:3000
   2022/08/31 10:29:54 cmd/web.go:221:listen() [I] [630f0df2] AppURL(ROOT_URL): http://localhost:3000/
   is just confusing. User cannot connect to server from outside to initial configuration

2. when setting addres from local net as AppURL e.g. 192.168.2.12:3000 server actually does not listen to that address, but continues response on localhost:3000.

3. user cannot connect to both external and internal addresses of a server

set ROOT_URL as your expected outside address

[NikolayUvarov]

then it does not work from inside. And I cannot set that url from outside via web console because I cannot access to console from remote. | can see that server works via wget localhost:3000 but not from 192.168.2.12:3000

[lunny]

That's another issue which has been reported in #19345

[NikolayUvarov]

please help: what should i do when internal access URL is http://192.168.2.12:3000/
and external is http://11.22.33.44:8000/ ?

I will try to answer some questions, and at the same time, you could understand more about your system and environment.

1. when starting configuration server listens localhost and not 0.0.0.0 as stating in its log, so
   2022/08/31 10:29:54 cmd/web.go:217:listen() [I] [630f0df2] Listen: http://0.0.0.0:3000
   2022/08/31 10:29:54 cmd/web.go:221:listen() [I] [630f0df2] AppURL(ROOT_URL): http://localhost:3000/
   is just confusing. User cannot connect to server from outside to initial configuration

Since Gitea shows Listen: http://0.0.0.0:3000, then it's already listening on all IP addresses.

AppURL is just for UI display and URL construction, it does nothing to the Listen address.

If user can not access it, please check your firewall (nat, etc) or other rules.

2. when setting addres from local net as AppURL e.g. 192.168.2.12:3000 server actually does not listen to that address, but continues response on localhost:3000.

Which address?

3. user cannot connect to both external and internal addresses of a server

If Gitea is listening on "0.0.0.0:3000", it should work. Check your firewall and environment. Plenty of users use the same setting and do not have such problem, and there doesn't seem to be a problem indeed.

[NikolayUvarov]

Yep, you was rigth about firewall, despite iptables-save was empty, some rules still persisted.
Thank you for clue.
