How to raise a proxy available from outside on a PC?
Maybe there is an easier way, you can tell me..

Answer 1

To connect to a proxy, a white IP must be used.
If you have Internet from your phone, ask the operator how to activate the "white IP" service, because. By default, all Internet users from operators sit behind NAT.

Answer 2

You need a white (dedicated) ip.
Usually bought from your provider for 100-200 rubles per month (if such a service is provided at all).

Answer 3

Can I use a white ip from the main provider.
And on the local network will connect to the mobile network?

Can I use third party software to set up a proxy server on my phone?

Answer 4

Yes, it is possible
And yes, it is possible in frequent cases when ip is gray (or rather dynamic)
To do this, you need access to a router that distributes wifi, you need to enable port forwarding in the nat settings (this can be called forwarding, port forwarding, and even something like set up a server on the local network), you need to specify the port outside, the ip address of the machine on the local network and the port on which the service is configured (it may differ from the open port outside)
About a dynamic ip address, the provider can issue an external address temporarily, often - for a day, after a lapse of time it changes (or not). But you can configure dyndns (this is an external dns server that provides a way to inform the dns server that the ip address has changed), you will get a domain name like vasyapupkin.dyndns.org (there are a lot of dyndns providers, including standards for how changes are reported about ip address), many routers support a couple of popular ones, providing the corresponding item in the settings.
Then from the outside it will be possible to connect not by ip address, but by a domain name, which at any time will return the current address (the exception is those few seconds or minutes while the ip address is changing and updating information about it)
ps Rarely (often with mobile providers or when the network was converted from a home network (straight from 200x) and not upgraded according to normal) there is basically no external access from outside, even upnp does not work (this protocol allows applications on the local network to automatically request opening ports on a forwarding router). You need to run away from such underproviders, away ... the maximum you can tolerate is if there is a very good price there.
