PIX 515 responding to ARP commands...
I have a strange thing on my network...
Setup is 5x 3com SuperStack Switches, 3x HP DL 380's, 1x NetApp Filer routed through to 1x PIX 515e.
So my problem is that occasionally I lose a device off the network. It won't completely drop from the network, but my machine will lose any kind of connection to it. The same might happen from a different machine, but not at the same time. Random machines will lose connection to another random machine at random intervals!!!
The confusing thing is that when the machine 'disappears', the PIX replies to the ARP request!!!
I have Packetyzer monitoring the network traffic, and I see an ARP request going out from my machine, and then the PIX replying to this ARP request. But this only happens randomly, and as I say, with random machines.
I've removed Broadcast Storm control from the 3com's, no VLAN's are in place, and no special routing is setup on the PIX. I can setup static ARP records on the PIX, but this isn't an ideal solution, and is it going to stop the PIX replying with it's own MAC address?
