Note
: a DNS server IP address of 127.0.0.1 means that Lync Server is using a DNS server on its own hardware.
Instead of entering 127.0.0.1 on the Expressway, use the IP address of the Lync Server platform instead.
On each Gateway Expressway peer:
1.
Go to System > DNS.
2.
If the DNS server that Lync Server uses can provide all DNS lookups needed by Expressway:
a.
Set Default DNS Server Address 1 to the IP address of DNS server noted earlier.
b.
If Lync Server has more than one DNS server defined, configure the additional default DNS server fields
(Address 2, Address 3 and so on) with the IP addresses of the additional servers.
(Address 2, Address 3 and so on) with the IP addresses of the additional servers.
3.
If the Expressway must use other DNS servers for normal calls and only the Lync DNS server for Lync access:
Configure the Default DNS servers with the servers which will be used for normal, non-Lync related DNS
operation and configure the Per-domain DNS servers section as follows:
operation and configure the Per-domain DNS servers section as follows:
Address 1
IP address of the DNS server used by Lync Server
Domain names
Domain shared with Lync
Address 2 … 5
Use these fields only if Lync Server uses more than one DNS server
Domain names
2 … 5
2 … 5
Use these fields only if Lync Server uses more than one DNS server; configure with the
domain shared with Lync
domain shared with Lync
4.
Configure the next available Per-domain DNS server address to contain the IP address of the Lync Front End
Server, and specify the Lync domain e.g. example.com as the associated Domain name.
Server, and specify the Lync domain e.g. example.com as the associated Domain name.
(This is required in some network setups: Lync frequently embeds hostnames inside contact headers and
sometimes these can be unresolvable outside of the Windows domain.)
sometimes these can be unresolvable outside of the Windows domain.)
5.
Click Save.
Enter System Host Name and DNS Domain
Give each Gateway Expressway peer a unique System host name and check it has the correct DNS Domain:
1.
Go to System > DNS and set:
a.
System host name to a unique hostname for this Expressway.
b.
Domain name to the domain name for this Expressway.
2.
Click Save.
Note:
■
Concatenate System host name with Domain name to get the routable FQDN of this Expressway
■
These items must be configured to properly enable TLS between Expressway and Lync Server environment.
If they are not, the neighbor zone may go active and Expressway may send messaging to Lync Server, but
Lync Server will never open a TLS connection back to Expressway.
Lync Server will never open a TLS connection back to Expressway.
Task 2: Enter a Cluster Name
Lync will be configured with a static route that always uses the Gateway Expressway's cluster name / FQDN.
For each Gateway Expressway peer (even if there is only one), ensure that Cluster name (System > Clustering >
Cluster name) is the FQDN of the cluster. You would have created the FQDN when setting up the cluster. See
Expressway Cluster Creation and Maintenance Deployment Guide for details of changing the cluster name.

Task 3: Configure an NTP Server
