Network Design/Engineering

Security and infrastructure hardware investments depend on solid engineering. The entire landscape needs to be considered. All too often we see the external threat profile driving the process. Considerations such as redundancy, threats from the inside, future scaling needs and efficiency considerations get left behind. With Realnets you will get a well-rounded assessment that drives to bring ROI via a reduction in capital expenditures, elimination of unneeded and costly downtime and the benefit of a full team of engineers at your disposal.


WAN Implementation and management

When selecting a wide area network uplink/internet service provider it’s good to have a partner that knows the landscape and the options available. Providers such as AT&T, Comcast, Covad, WOW and Level 3 bring a variety of service options with price points that can make an assessment quite complicated.  Realnets brings an agnostic review of the options and an experienced project management team that can assist in installations by third party vendors. Realnets has implemented private and cloud-driven point to point copper and fiber optic circuits including the design of MLPS networks. In addition, we routinely specify, order/manage installations of Comcast Business and WOW broadband services.



Different size networks have a variety routing needs. Bordering with other networks, sharing routes with 3rd party networks or building larger campus environments require engineering and documentation.  Realnets has dreamed up some pretty unique solutions to some pretty complex network routing problems over the years. Our experiences with routing protocols include  RIP, IGRP, EIGRP,  BGP, and OSPF. In addition, we bring experience in ARIN privately owned IP space management.   Hardware routing experience includes Juniper, Cisco, HP and many other brands along with the ability to configure cloud platform routing from AWS and Azures.

Firewalls – IDS – IPS

Implementation and ongoing management of your Firewall can be a critical element of your business. Often these devices (or virtual instances) can be a single point of failure for mission-critical traffic or a potential open portal for an onslaught of threats to your business. The landscape has changed very quickly in this space. Perhaps your servers are being replaced every 4 to 6 years… In the firewall space, anything over 3 years of age with regards to a fixed state solution is going to be substantially behind the curve.

The next-generation in unified threat management devices took us out of the “dark ages” of security. Unfortunately, many people haven’t discovered or deployed these technologies and thus remained exposed to many threats. The key to the engineering and deployment of your solution is in the profiling of your services as related to the execution of a full-throated Intrusion Detection System (IDS) / Intrusion Prevention System (IPS). Web server, service based and email filtering are cornerstones to a secure environment.

Realnets has implemented IPS/IDS/firewall solutions, open source and paid. We have extensive experience with, Shorewall, IP Tables, Alert Logic, Sonicwall, Sophos SG, Sophos XG, AWS NAT / NACL, Azure and Cisco solutions.


Virtual Private Networks

Realnets brings a wide variety of past project experience in the VPN space. Cross connecting platforms, sites and end users can be a complex web of technologies and security considerations. Remote Access VPN or road warrior solutions such as OpenVPN are common projects. Site – to – Site VPN projects often are complicated by solutions like Cisco PIX on one side and Amazon AWS on the other. Internet Protocol Security or IPSec as a requirement when one end has a dynamic IP was once a request of us in southern China. Layer 2 Tunneling Protocol (L2TP) project utilizing protocols such as Cisco’s GRE often are driven by VoIP projects.  Point – to – Point Tunneling Protocol (PPTP) often are implemented in campus cross connection projects. Punching through firewalls and other 3rd party networks often requires Realnets to utilize Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols.

Realnets has extensive OpenVPN experience with a dozen of projects delivered with very complex configurations in many cases. Custom OpenVPN solution development is also available, many projects require key and authentication integrations not possible with other solutions.


It doesn’t really matter what hardware you have, we’ve worked with it. From Cisco to brands that don’t exist anymore we’ve replaced, installed and implemented switches from 4 ports to 500 port. POE, Multi Mode Fiber, 10G, 40G, 1G, we’ve pretty much worked with every port type and speed. HSRP, dual homing and spanning tree are common focal points. Designing networks for built-in redundancy are at the core of all our design considerations. HP and Cisco network hardware are core competencies.
