Proxy-arp & reply-only

RouterOS General
1

Hello,

I would like to enable proxy-arp & reply-only (yes, these two options) on my Local bridge interface. Is something like that possible or how to do functionality like this?

Regards, Kamil.

(feature request ?) ARP mode : local-proxy-arp + reply-only

That might be possible, and I haven’t tried this, by putting the interface(s) in proxy-arp and then add a bridge filter rule to throw out incoming ARP packets.

Hey,

Thanks works great, as expected :wink:

/interface bridge filter add action=drop arp-opcode=reply chain=input comment="Drop ArpReply packets" \
    disabled=no in-bridge=Local mac-protocol=arp 
/interface bridge filter add action=drop arp-opcode=request chain=output comment="Drop ArpRequest packets" \
    disabled=no mac-protocol=arp out-bridge=Local

It’s strange that I didn’t think about it before :wink:

Regards, Kamil.

Hey,

Yes, of course. My network is divided into many small subnets (every MT has own subnet). Client receives mask which includes all subnets, then proxy-arp does job. However, I also want to have static arp entries for clients (it’s done by DHCP-Server) that’s why I needed reply-only. It’s just only for LAN. If client want to access to the Internet it has to use PPPoE and there are of course different queues for Lan and for the Internet.
