Hi Ross, as far I understood, you configure a static NAT for each IP address you reserve for AV services on your SFB edge servers. In this way the traffic from external clients goes "directly" to the edge servers. I do not figure out how if these NATs are balanced. Are you using DNS round robin for SFB AV services? Or maybe SKFB does not need that an "unique" public DNS record is set up for AV services? Regards MM

    The S4B client will use TURN/STUN protocol to find the "best" AV server it can communicate with. The NAT is used to make TURN/STUN protocol to work directly with the AV host. The load balancing decisions are done in your Skype AV pool topology(within the skype topology itself and directs the client to a specific AV server.)
