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. When users select the Dynamic IP in Remote Security Gateway Type, it will be limited as Aggressive Mode.
Compress (Support IP Payload compression Protocol (IP Comp): The Router supports IP Payload Compression Protocol. IP Payload Compression is a protocol to reduce the size of IP datagrams. If Compress is enabled, the Router will propose compression when initiating a connection. If the responders reject this propose, the Router will not implement the compression. When the Router works as a responder, the Router will always accept compression even without enabling compression.
AH Hash Algorithm: AH (Authentication Header) protocol describe the packet format and the default standards for packet structure. With the use of AH as the security protocol, protected is extended forward into IP header to verify the integrity of the entire packet by use of portions of the original IP header in the hashing process. There are two algorithms, MD5 and SHA1. MD5 produces a
NetBIOS broadcast: Check the box to enable NetBIOS traffic to pass through the VPN tunnel. By default, RV0041 blocks these broadcasts.
Click the Save Settings button when you finish the settings or click the Cancel Changes button to undo the changes.
