Adds a warning to the Internet access page explaining that, due to how outbound TCP traffic is routed to the egress firewall, a TCP connection from inside the sandbox can appear to succeed even when the destination is denied by
denyOutrules — no packets actually reach the destination.Recommends checking for an application-level response (HTTP status, TLS handshake, etc.) to verify that traffic is actually flowing.
Context: internal thread clarifying that the firewall must accept the connection first and use a syscall to retrieve the original destination IP before applying egress rules.
