How Do I Control Being Pingable or Stealth?
The following is for the BEFSR41. Note that “SPI” was removed in recent firmware so does not apply. “Pingable”: “Block WAN Request” Disabled and “SPI” Disabled. TCP “Stealth”: “Block WAN Request” Enabled or “SPI” Enabled or see UDP “Stealth”. UDP “Stealth”: Set a dummy-IP in DMZ. This also runs TCP “Stealth”. (warning: reported to cause instability) Note: Enabling “SPI” disables all port forwarding and DMZ.
