Establishing a direct link to your server.
Establishing a direct link to your server.
This approach could work but depends on your setup. Setting up a network to restrict server access while keeping it reachable from your main devices is feasible. Using a MikroTik switch and configuring firewall rules would help control traffic. Reddit suggestions point toward subnetting and client-initiated connections, which aligns with your goal. Software options like pfSense can assist in managing access, though you may need additional hardware for optimal performance. No immediate purchases required unless you decide to expand the setup later.
It's not about remote access per se. I want to isolate my server from the network, preventing it from being reachable while still letting internal queries pass through. Ideally using software on a Linux machine.
Confirming the setup: the server is either on your local network or a remote internet server. On Linux, you can manage security with iptables or nftables. If the server is online, restrict all outgoing connections while keeping necessary ports open for remote access. Ports like DNS and HTTP should remain active, but others can be limited to only exit your network. For instance, the nftable rules on my server include filters for incoming traffic, allowing specific IPs like 'localhost' and certain protocols while blocking others. Some ports must stay open, and you can set limits on outbound traffic to prevent unauthorized access. Remember, a local firewall won<|pad|> can block essential services, so ensure critical ones stay enabled. If compromised, relying solely on a local firewall isn't sufficient—network-wide rules are essential for robust protection.
It's a very thorough explanation. I hope you'll consider adding a Raspberry Pi or something similar to your setup between your server and the rest of the network. This would help block any incoming traffic. Your server already has security in place, but having an extra layer adds extra protection. Thanks! Stay safe!
It seems like your concerns about security are valid. If the server is vulnerable, any access from another client on the network could pose a risk, even without direct connections. If it's already on the WAN side, you should be able to reach it normally. Also, make sure the server and your router use the same WAN IP addresses.
