How will Bitrix work with the port?

Question

linux

Good day, the situation is as follows:
The organization has an external ip-address, let's say 20.20.20.20 , behind this address lies the organization's service and in the registry a domain is attached to this address, let's say service.rus . The organization also has a Bitrix.Corporate portal that runs on a server inside the Bitrix VM and must also be accessible from outside. A redirect was made through the router and after 20.20.20.20:333 the user gets to the Bitrix authorization page, but immediately after the user passes authorization and Bitrix sends him to any other page, the service.rus domain name appears in the address bar and the user is on the page the main service of the organization.
The question is, what manipulations need to be done in order for Bitrix to work correctly through port 333?
Thanks in advance

Answer 1

What is the internal port of Bitrix, 443? - so it will not work
What can you think of.
- change port 443 to 333 on the Bitrix server - but this is crap, you will come here again when your Bitrix clients fall off, there will be problems with the web socket.
- use nginx proxy and resolve access to web resources by domain name.

Answer 2

Take another ip to forward to the internal portal, put it on b24.service.rus and don't suffer.
Access through ip + port will not lead to anything good.
Try setting the address along with the port in the settings

Answer 3

1. It is necessary to create a service.rus DNS zone inside the organization and in it a bitrix.service.us DNS record with an internal ip
2. Change the bitrix portal name settings to bitrix.service.us
3. create the same record in the external DNS but with an external ip .
