MPTCP aspirations Being able to separate the lifetime of a connection from the lifetime of a flow allows MPTCP to address two problems present in classical TCP: aggregation and mobility. Aggregation : MPTCP can aggregate the bandwidth of many network interfaces. A single flow can make use of just one physical interface.

Advertising public IP addresses via Private VIF As mentioned above, we built the network path from our microservices to the Direct Connect Location, and the requests got exchanged to the on-premise data center. Since the vendor’s firewall only accepts traffic from public IP addresses, it is still denying all our requests.

The IP address of this service will be a public IP, and routable from the subnet. The key here is for the private resources to find a DNS resolve for that private IP address. The key here is for the private resources to find a DNS resolve for that private IP address.

Cato Networks is not aware of any malicious exploitation of its ZTNA using this technique. Details of the attack When a VPN client operates, it begins by creating an encrypted version of the original packet received from its virtual network interface. One of the advanced features of DHCP is Option 121, introduced in RFC 3442.

Flow logs are a valuable source of network traffic information in AWS. They capture detailed metadata about the traffic flowing through various components of your network, such as VPCs, subnets, and network interfaces. AWS Transit Gateways act as a centralized hub for connecting multiple VPCs and on-premises networks.

Flow logs are generated only from VPCs, subnets, and network interfaces. One way to quickly instrument this change is to configure flow logs on an interface basis. To do so, just navigate to the “EC2 > Network Interfaces” page in the AWS console and search for the string “gateway.”

TCP/IP is one of the fundamental networking protocols and the basis for common protocols like HTTP. IP address abstraction and failover capabilities with DNS Domain Name System (DNS) is a system for mapping domain names to IP addresses. This is another facet of network resilience.
