[c-nsp] Strange Arp Entries

[Matthew Melbourne]

What does your default route point to; this might be explained by a static
route towards an egress interface?

I have a simple cisco 2600 that has two fastethernet interfaces. The arp
table is filled with entries from ip's from all over the internet associated
with the wan interface. I have "no ip proxy-arp" turned on for both
interfaces. Any idea why the arp table might be filling up with this stuff?
