same arp entries on inside and outside

lcaruso — Mon, 11 Mar 2019 20:53:26 GMT

Hi,

I was having a problem pinging across a site to site vpn tunnel to this site, then I noticed the same inside devices showing up on the inside and outside during a show arp command.

This is ASA 8.4(2) 5505.

Is this a bug or what would cause this? Thanks.

Larry,

Is the switch on the outside connected to the switch on the Inside? Are you using only 1 switch? If so, is everything on the same vlan?

Hi Mike,

Those are the right questions to ask. I've passed them along to the onsite resource to see what we can find out.

Thanks much.
