Nortel VPN Router Configuration — Basic Features
The Nortel VPN Router supports the Internetwork Packet Exchange (IPX)
protocol. This allows the Nortel VPN Router to transmit and receive IPX packets
over PPTP.
The Nortel VPN Router supports IPX by encapsulating IPX traffic within IP
tunnels over PPTP. The private interfaces and public interfaces can carry IP and
IPX traffic simultaneously. The IPX addresses are not shown in the preceding
illustration.
Management virtual address
The management virtual address (MVA) is a reserved circuitless IP (CLIP)
address. The MVA is a unique CLIP address that is used only for management and
is separate from other CLIP addresses. Using a CLIP address ensures that there is
no dependency on any particular physical interface. This eliminates a single point
of failure. As long as there is a route through an interface to the MVA, you can
manage the Nortel VPN Router. Access to the MVA is supported on a public
interface through a VPN tunnel.
The following management protocols are available for MVA from the private side:
• HTTP
• HTTPS
• SNMP
• FTP
• Telnet
