 |
My VoIP ATA is connect to the router by the switch port.
I can accessed the VoIP ATA's web gui by entering its DHCP address on the web browser.
Is there a way to block access to the web gui and allow along specific devices via MAC? |

From within the same subnet you can maybe use ebtables? |
The source and destination ports are in the same subnet. How would you go about it with etables? |

I am sorry I have little experience with ebtables, it works in more or less the same way as iptables but then at Network layer 2 (MAC level)
