I ran Ethereal and captures all packets for 1 minute and 49 seconds.

What network? What is on this network?

TCP 353 70.2%
UDP 15 3.0%
ICMP 13 2.6%
ARP 122 24.3%

Fairly quiet - but without knowing _what_ you are looking at, it is
difficult to say if this is normal or not. For example, if you
are looking at a DSL connection, you are not likely to see any
mono-cast traffic (traffic to/from a single IP address) that is not
directed at your host. But you will _PROBABLY_ see all _broadcast_
traffic, where the router/switch does not know if "you" are the
destination or not.

Is this a normal ARP packet percentage? It seems a bit high to me.

Not enough information. The other question is what operating system
are the hosts running? That may also have impact on the traffic.

Old guy

little question don't routers split up broadcast domains ?
and thus broadcasts from the WAN side shouldn't be forwarded to the LAN
or does that in general only occurs in the reverse (eg from LAN -> WAN) ?
.
