Active Wall
Active Network CO
Active Wall uses the middle layer drivers developed independently as the filter engines, which are more low-leveled than other software which uses WinPCap. Because WinPCap is a protocol-type driver, it can only monitor but not block. The other software which uses WinPCap can only block TCP communications, but cannot block UDP, ICMP, IGMP data packets. It has been proved that Active Wall is more stable, correct and effective after working online for a long time. Most similar software support the only one mode- Passby monitoring mode. Besides the Passby mode, Active Wall supports more modes including Gateway mode, Bridge mode and Single mode. It is recommended that the users should use the Gateway mode or the Bridge mode. When using the Passby mode, Active Wall can only block TCP data packets for the limit of the network topology. However, the Gateway mode or the Bridge mode enables the Active Wall to block all kinds of data packets.Starting Price: $10 per user -
