Reference Manual for the ADSL Modem Wireless Router DG834G

Will either endpoint use Fully Qualified Domain Names (FQDNs)? FQDNs supplied by Dynamic DNS providers (see “The Use of a Fully Qualified Domain Name (FQDN)” on page B-8) can allow a VPN endpoint with a dynamic IP address to initiate or respond to a tunnel request. Otherwise, the side using a dynamic IP address must always be the initiator.

What method will you use to configure your VPN tunnels?

The VPN Wizard using VPNC defaults (see Table 7-2)

The typical automated Internet Key Exchange (IKE) setup (see “Using Auto Policy to Configure VPN Tunnels” on page 7-38)

A Manual Keying setup in which you must specify each phase of the connection (see “Using Manual Policy to Configure VPN Tunnels” on page 7-48)?

What level of IPSec VPN encryption will you use?

DES - The Data Encryption Standard (DES) processes input data that is 64 bits wide, encrypting these values using a 56 bit key. Faster but less secure than 3DES.

3DES - (Triple DES) achieves a higher level of security by encrypting the data three times using DES with three different, unrelated keys.

What level of authentication will you use?

MDS: 128 bits, faster but less secure.

SHA-1: 160 bits, slower but more secure.
