![]() ![]() This makes sure that complete user traffic goes through organization’s secure layer and thus client device is not vulnerable to attacks. ![]() OFF mode: All network traffic originating from user device goes through the VPN tunnel. ![]() Accordingly the Gateway plug-in takes the forwarding decision. Split tunnel on NetScaler Gateway can be configured as OFF, ON or REVERSE. The NetScaler Gateway Plug-in examines all packets transmitted on the network from the user device and compares the addresses within the packets to the list of intranet applications. When the NetScaler Gateway Plug-in starts, it obtains the list of intranet applications from NetScaler Gateway. NetScaler Gateway’s split tunnel capability allows the Gateway plug-in to decide which traffic to send to VPN tunnel and which not. ![]() By this they make sure that all Internet traffic goes through their forward proxy and (web) firewall and thus any possibility of compromising the user device to gain access to internal network is eliminated. In some cases, organization would like to secure their internal network from any kind of attack by making sure that all traffic originating from user device goes though it’s network. Internet traffic going to NetScaler Gateway adds lot more hops in reaching the servers and thus in getting the response back on user device. The success of this task rests on the strategic preparation and operational management of risk and safety in a challenging rural environment.Sending all user device originating traffic, including Internet traffic, through VPN tunnel might not be desirable in most cases. The purpose of this paper is to describe the key engineering and planning components involved in this operation including pre- and post-grouting, chamber crane, sonar, local water compensation, jet flushing, drilling, caisson installation, and concrete design, production, delivery and placement. In addition, the power station ball valves have seized ajar and the damaged intake riser is unsafe toaccess thereby requiring the plugging operation to be carried out under live flowing conditions.Working under hydrostatic pressure and live conditions, the headrace plug will be an underwater tremie pour operation that includes drilling and concrete injection through blow out preventer caissons installed in the floor of an underground chamber above the tunnel. The headrace tunnel is part of a closed waterway system that connects the dam via a shaft, exhibiting a hydrostatic pressure of 13 bar (1300 kPa) at the location of the new tunnel plug. A major component of these works is the decommissioning of a section of the seven metre diameter headrace tunnel by installing a concrete plug. However, due to landslide erosion and prolonged silt infiltration caused by an earthquake in 1990, the power plant has been rendered inoperable since 1999.To bring the power generating facility back to life, the project scope entails the rehabilitation and construction of civil structures, shafts and tunnels. When it was built in 1956, the Ambuklao Dam harnessed the second largest hydro-electric reservoir in Asia. The Ambuklao and Binga Rehabilitation Project is a 175 MW hydro power project currently under construction across dual sites in the north region of Luzon Island, Philippines. ![]()
