Dear All,

I tried to and configure a setup with 3 nated ips for our edge server. I have create nat VIPs on our firewall with three public ips pointing to three DMZ ips of edge server for port 443.I have configure additional interface on lyncedge for internal network.Ihave also configure route add rules on edge server.I have aslso specify on topology builder hte external public ip of av.The replication between lync and lync edge is succesfull. Unfortunately is not working as expected . when user outside the netwowork calls someone the phone is ringing and when answered lync stuck for 5-6 seconds on connecting call and then fails. On the firewall logs i can see drop connection that is trying te reach external client to its internal ip instead of firewall external ip i suppose. What could be wrong?

OK finaly it was a rule which i forgot to create on the firewall.
