Flush bridge / arp cache ? Cannot reuse interface IP when removed

Hi everyone,

I have a strange behavior with my endian firewall (3.0.0.devel).
I have my red Interface on a /27 public subnetwork which allows many IPs.

I removed 1 ip (using the webui, main uplink) because I want to use it in a different server in the same network.

The server is able to acces the internet and can contact other servers on the same subnet (public). However, LAN interface on the endian is not able to communicate with this server.
If I use another IP (same subnet, same interface) on the server , which has not been used in the Endian,  it works. So I think there is a kind of cache in the Endian, it still thinks this IP is local even after deleting. It's probably with the br0 bridge.

using tcpdump I can see my target server receiving echo_request and sending echo_reply, however on the endian I can see these reply on my ethX but not on the bridge, which is not normal.

Thanks.
