There are three cases in which Wave allows for PPTP:
• Packets with TCP source port 1723
• Packets with TCP destination port 1723
• Packets using IP protocol number 47, which is the Generic Routing Encapsulation (GRE)
protocol
A total of six additional filters must be in place, with the filters set to drop all except those listed
below.
Network services
Wave uses the following Windows services for network information services:
• Dynamic Host Configuration Protocol (DHCP)
• Domain Name Service (DNS)
• Windows Internet Name Service (WINS)
By default, Wave does not use DHCP and can be easily configured to be a client of WINS and
DNS.
