# Network Block/Allow

The IP &amp; Network Override section will allow you to Permit or Deny specific IPs or Networks. The permit or deny action will occur at the perimeter check level. If the action is permit, then the perimeter checks will be effectively bypassed and the email will be allowed to be processed by the rest of the subsystems such as the spam filter and the antivirus engines(s). If the action is deny, then the connection will be immediately dropped by Hermes SEG and no further processing will occur.
