A Network Address Translator (NAT) allows hosts in a private address space to communicate with servers in the public Internet. There is no accepted solution for an arbitrary host in the Internet to initiate a communication with a host located in a private address space despite the efforts to create one. This paper proposes to replace NATs with a new concept we call Private Realm Gateway (PRGW). Private Realm Gateway creates connection state based on incoming DNS queries towards the hosts in the…

Securing the Private Realm Gateway

This paper analyses the security of PRGW and introduces mechanisms that protect the served hosts and networks against Internet-borne attacks, in particular: address spoofing and Distributed Denial of Service (DDoS).

Traversal of the customer edge with NAT-unfriendly protocols

The proposed approach significantly cuts the session establishment delays typical in SIP and the implementation of Application Layer Gateways for these two protocols is reported and guidelines for processing other protocols are provided.

The presented work is a part of a larger project that addresses many issues of the current Internet and proposes the use of CES as collaborative firewalls to reduce volume of unwanted traffic and mitigate Denial of Service (DoS) attacks in the Internet.

Transition to IPv6 with Realm Gateway 64

The paper shows that RGW64 is suitable for operators who want to gradually migrate customer networks to IPv6 yet maintaining reachability with the IPv4 Internet, which does not require changes in end-hosts.

Sec-ALG: An Open-source Application Layer Gateway for Secure Access to Private Networks

This paper presents a novel open-source ALG, called Sec-ALG, for providing secure end-to-end communication to the web servers situated in the private address space, that relies on the technique of light Deep Packet Inspection (DPI) for protocol detection and session establishment using a novel parser-lexer generator called YaLe.

Performance of Cooperative Firewalls in Real-World Deployments

An analytical model was developed to estimate the performance in terms of session setup delays and number of servers required for the Customer Edge Traversal Protocol (CETP) to support a large number of IP-based devices.

A NAT traversal mechanism for cloud video surveillance applications using WebSocket

This paper describes a novel Video Surveillance as a Service (VSaaS) architecture that uses an add-on component, named WS-Gateway (WebSocket-based gateway), installed in the client’s private network (along with IP-cameras network) to establish a bi-directional communication among the actors in the system.

Policy-based communications for 5G mobile with customer edge switching

This paper proposes a system controlled by policy that overcomes the classical weaknesses in the Internet, namely source address spoofing and denial of service attacks and proposes to improve the mobile device experience by new methods of network address translator traversal suitable for battery-powered mobile devices.

Attack Resistant Services Delivery over the Internet

The tests done in this thesis show that the Realm Gateway system works well against DoSand DDoS-attacks in some cases and it offers good ideas in the network security and service availability context, but to make the system fully feasible in practice, the RealmGate software itself should be reĄned, updated and tested further.

Proposal of a NAT traversal system independent of user terminals and its implementation

This work proposes a new NAT traversal system which does not need to modify terminals (it needs to modify the DNS server and the NAT router though).
