I’m building a very small PoC that reflects a situation we’ve encountered in the while: somewhere between our software client and a remote server, a firewall is dropping idle connections. The client doesn’t receive a RST or FIN and this leads to Bad Behaviour. I’d like to use VYOS as the firewall. I have read through much of the documentation but didn’t find out how to do this.
Could someone provide me a hint? The goal in a nutshell: an idle connection is silently dropped after a configurable timeout is reached.
