Deploying Microsoft Office Live Communications Server 2005 and the F5 BIG-IP LTM System v9
BIG-IP® Deployment Guide 20
Prerequisites
The following are prerequisites to the Access Proxy configuration.
◆ In the following procedures, we assume you have already created pools
for the Live Communications Servers, as shown in Creating pools, on
page 1-6, and virtual servers, as shown in Creating virtual servers, on
page 1-11.
If you have additional pools of Live Communications Servers, repeat the
procedures in Creating pools, on page 1-6, and Creating virtual
servers, on page 1-11 for the additional Live Communications Server
pools, and then return to this section.
◆ If you have a firewall in your network in between the Internet and the
BIG-IP LTM system (as shown in Figure 12), the firewall needs to be
configured to allow TCP traffic on port 5061 in both directions, and
TCP/UDP traffic on port 53 for outbound traffic only.
◆ If you have a firewall in your network between the Access Proxy devices
and the inside BIG-IP LTM system (as shown in Figure 12), the firewall
should be configured to allow only port 5061 traffic in both directions.
◆ The default gateway on the Access Proxy devices should be the IP
address of the internal facing self IP on the outside BIG-IP LTM system.
◆ If you are using a Director in your deployment, you must modify the
Hosts file on the Access Proxy devices to resolve the Director fully
qualified domain name (FQDN) to the virtual server address of the
Director.
Configuring the BIG-IP LTM systems to direct traffic for the
Access Proxy
Note that this Best Practice configuration requires two additional BIG-IP
LTM systems to load balance traffic to the Access Proxy devices.
In the following sections, we first configure the outside BIG-IP LTM
system, then the inside BIG-IP LTM system.
Important
We assume the BIG-IP LTM systems are already installed in the network,
and that you have created (or are using the default) VLANs on the external
and internal network. If you need to create additional VLANs, see Creating
a VLAN, on page 4.
Configuring the outside BIG-IP LTM system
We begin this deployment by configuring the outside BIG-IP LTM system
(as shown in Figure 12). On the outside BIG-IP LTM system, you need to
complete the following procedures:
