What is the best solution for a corporate server?

Question

Network routing

Good time of the day.
There is a server with OS Proxmox, everything suits and everything is great.
At the moment, everything will be redone anew with a number of network structure changes and hardware upgrades.

Now the picture is this:
Internet-router-server

On the server is a web server
File storage and much more

And the question is, does it make sense to use a router router?
The router now just limits the ports and that's it.

Which system will be better?
1) internet-server
2) internet-router-server

Answer 1

I would put router. It is easier to make network settings on it (for example, nat, firewall, qos), there is less chance of error, it is easier to replace the server behind it if necessary, a decent router has better network performance and it will cut off part of the left requests (for example, scanning) and reduce the load on the server .
