Continuous ARP boradcasts on WAN side...

[jagdtigger]

Hi all.

 

So i noticed that lately the indicator on my wan port always flasing ven if there is 0 traffic from/to LAN(LAN port not flashing). Plugged directly into moden and this is what i saw in wireshark:

It doesnt seem to effect my internet speed ATM, but it poked up my curiosity because normally my connection on the wan side is idle when there is no active connection from the LAN....

 

Should i worry or just ignore this?

Completely normal. There's always going to be a ton of various broadcast traffic.

It's nothing compared to any other type of traffic. It'll be the last thing to bug down your router

Likely just proxy arp traffic.

 

Also your provider is utilizing some private space.

 

It's just normal IPv4 traffic, your router participates as it's part of that network.

There is always broadcast traffic, it hurts you ISP more than your connection. Its all good and normal.

Okay, but 26+ packets in a second seems a little bit excessive to me...

Based on what premise?  They're literally 64 bytes per packet...

On my experience that in the past my modem would sit idle if no-one used the internet?

26 packets pr second is nothing. On a gigabit line you could exceed more than a million packets pr second. Your router won't ever sit completely idle. It is always going to communicate with something.

Broadcast packets are when others are using the internet, not you. The is always going to be WAN activity on a large network
