17.7 Legacy Series / Enable ARP replies on WAN network
« on: August 02, 2017, 12:33:08 pm »
I recently brought up a OPNSense firewall that has to accept connection from multiple IPs on the same subnet from the WAN interface.
The default gateway is connected on the same interface and on the same subnet of the other devices.
However, it seems that OPNSense accept connections only from the default gateway.
After some investigations, I discovered that OPNSense seems to reply only to ARP request that comes from the default gateway on the WAN interface.
Can you please help me in order to enable ARP replies from any device on the WAN interface that belongs on the same network?
Thank you and best regards
