We want to test S4B mobility....is it possible this scenary ??:
1) External (Public) DNS record (A)... S4BEXT.CONTOSO.COM pointing to IP1
2) We convert (NAT) IP1 to IP2. IP2 is a TMG IP
3) We publish S4B Services on TMG
4) We configure Lync Mobile Devices manually point to S4BEXT.CONTOSO.COM
Note: At this moment, we want to avoid create Lyncdiscover record......
Thanks
