Redirect ignored on red

Networking
1

HI all,

I have regulary this in my log on my red interface :

IPv4: Redirect from **192.168.1.254** {proxmox-red.yannick.lan} on red0 about **192.168.1.1** {livebox.yannick.lan} ignored

Advised path = **192.168.1.250** -> [194.177.34.116] {router-ix5.servme.network}

Any ideas what’s wrong ?
I have some home automation equipment on the red lan.

My red lan :

IPFire (VM on Proxmox) red interface : 192.168.1.250
Proxmox red interface : 192.168.1.254
My Box : 192.168.1.1

Thx by advance

Hello,

you seem to have a misconfiguration in your network. It looks like the Proxmox machine has configured itself as the default gateway to your firewall (I have no idea how that happened) and is now telling the firewall that it should send packets to hosts on the internet to a different gateway (your router).

ICMP redirects are a potential security risk which is why IPFire is ignoring them on RED.

Just configure your router as the default gateway for IPFire and you will be fine.
