How to Modify the DVS Uplink Security Policy?

I'm trying to use a DVS to play pcaps out of a physical interface, then back into another physical interface on a different DVS. My pings are going through just fine, but when a pcap is replayed, the traffic is dropped.

I believe the traffic is being dropped because MAC Address Changes are being rejected...or possibly because Forged Transmits are not actually accepted. The port group for this DVS has a security policy set to Accept everything.

How can I configure the security policy for the uplink interface?

Thanks in advance!
