RTIDDS Ping QoS

Hello,

I am completely new to RTIDDS, and I have been having trouble getting two of my machines to ping each other. I have checked on them using the Admin Console and have found that the problem is a mismatch between their Durabilities in the OoS, the publisher being set to VOLATILE_DURABILITY and the subscriber being set to TRANSIENT_LOCAL_DURABILITY. So, I tried going into the QoS that was provided with the RTI launcher and adding in a policy in the publisher that sets the durability.kind for the datawriter to TRANSIENT_LOCAL_DURABILITY. But, it seems like it didn't take because when I try to ping again it still displays the same problem.

So my big question is: Is there something I need to do when I change the durabilty in the QoS besides simply adding some tags to set the durability to TRANSIENT_LOCAL_DURABILITY?
