Northwind Traders has a Lync 2013 deployment. The company has outsourced the help desk to a third-party service provider that is located in New Delhi. The service provider has a 10-MB site-to-site virtual private network (VPN) connection to Northwind Traders. The service provider uses a proxy server to route and monitor traffic to Northwind Traders. Both sites' computers are on the 10.10.1.x/24 subnet. The proxy server's Northwind Traders-facing IP is 192.168.1.100.
