ARP on a PIX 515

I am Connecting to a new Centurylink IA service. My handoff is from an AdTran router. I have a basic config on my firewall with NAT. My speed is very slowbut port interface counters are clean. Provider is insisting they don't see ARP from me. Is there a way I can confirm my firewall is sending ARP upstream?

ARP on a PIX 515

Do you happen to disable proxy arp on your interface? By default proxy arp is enabled on PIX.

Check out if you have the following:

sysopt noproxyarp outside

The above will disable proxy arp, if you need to enable proxy arp:

no sysopt noproxyarp outside
