How to create a container without default route with Internet access?

General

Hello.
There is a rootless podman container.
The task is to make sure that there is no default route inside the container, but there is a network and access to the Internet.
Internet access means access to the router subnet: 192.168.1.0/24.
The following options do not help:

--network pasta:--no-map-gw
--network pasta:-a,10.0.2.0,-n,24,--no-map-gw,--no-dhcp

the network is created and the default route is copied from the host.

It turns out to be done like this:

podman exec --privileged -u 0 -ti firefox bash
ip route del default
ip r add 192.168.1.0/24 dev enp0s7

But this must be done every time, which is not a convenient or smart solution.

Please tell me, is there any solution so that there is no default route?
Thank you.

Why would you expect this to work?

You don’t even use docker… did you accidentally post in the wrong forum?

In docker you can create networks using --internal to prevent them having internet access (see: here)
