Firewall Information for the Agent

The Agent makes outbound-only connections to Files.com over standard HTTPS. It operates inside typical enterprise firewall and NAT environments without inbound rules, port forwarding, or exposing internal systems to the public internet.

The Agent uses one network port for data transmission and one for DNS lookup. It does not require any inbound network ports.

Data Transmission

The Agent uses a single outbound network port, port 8801, for data transmission. This port cannot be customized.

The Agent uses both the UDP and TCP protocols. It first attempts to connect over the faster UDP protocol and falls back to TCP if UDP is unavailable.

The Agent connects to Files.com using the general pool of Files.com IP addresses. Make sure that outbound connections to these IP addresses using port 8801 are allowed through your firewall.

If your Files.com site uses a custom domain, the Agent connects using your dedicated IP addresses instead.

DNS Lookup

The Agent uses a single outbound network port, port 443, for DNS lookup. This port cannot be customized.

The Agent first attempts to look up public DNS information using https://cloudflare-dns.com. If that connection fails, the Agent falls back to the local host's DNS settings.

Make sure that outbound connections to either https://cloudflare-dns.com or to your designated DNS servers, using port 443, are allowed through your firewall.
