Encryption— The Encryption method determines the length of the key used to encrypt/
decrypt ESP packets. 3DES is supported. Notice that both sides of the VPN tunnel must use the
same Encryption method.
Authentication— Authentication determines a method to authenticate the ESP packets. Either
MD5 or SHA1 may be selected. Notice that both sides (VPN endpoints) must use the same
Authentication method.
• MD5— A one way hashing algorithm that produces a 128-bit digest.
• SHA1— A one way hashing algorithm that produces a 160-bit digest.
Perfect Forward Secrecy— If PFS is enabled, IKE Phase 2 negotiation will generate a new key
material for IP traffic encryption and authentication. Note: that both sides must have this
selected.
Preshared Key— This field specifies a key used to authenticate IP traffic. Both character and
hexadecimal value are acceptable in this field. Note: that both sides must use the same
Authentication Key.
Inbound SPI/Outbound SPI—The SPI (Security Parameter Index) is carried in the ESP header.
This enables the receiver to select the SA, under which a packet should be processed. The SPI is
a 32-bit value. Both decimal and hexadecimal values are acceptable. e.g. "987654321" or
"0x3ade68b1". Each tunnel must have unique an Inbound SPI and Outbound SPI. No two
tunnels share the same SPI. Notice that Inbound SPI must match the other router's Outbound
SPI, and vice versa

Status

This field shows the connection status for the selected tunnel. The state is either connected or
disconnected.

Buttons

Connect—Establish a connection for the current VPN tunnel. If you have made any changes,
click Save Settings to first apply your changes.
Disconnect—Break a connection for the current VPN tunnel.
View Log—View the VPN log, which shows details of each tunnel established.

Advanced Button

Aggressive Mode—There are two types of Phase 1 exchanges: Main mode and Aggressive
mode. Aggressive Mode requires half of the main mode messages to be exchanged in Phase 1
of the SA exchange. If network security is preferred, select Main mode.
NetBIOS broadcast—Check the box to enable NetBIOS traffic to pass through the VPN tunnel.
By default, WRVS4400Nv2 blocks these broadcasts.
Click the Save Settings button to apply your changes or Cancel Changes button to cancel.
