WAN Implementation and Management

Wide area networking (WAN) is the industry standard for connecting all aspects of your business across multiple locations with optimal privacy and security. Implementation and management of these solutions, however, can become quickly overwhelming – even for businesses with a dedicated internal IT service team.

At Realnets, we are proud to be your chosen WAN implementation and management partner. We are very familiar with the options offered by major providers, such as AT&T, Comcast, Covad, WOW, and Level 3, and we provide you with an entirely neutral review of these third-party organizations. We can walk you through the various levels of service and price points, consulting with you to determine the best course of action according to your company’s unique business needs.

Enterprises with a higher-than-average demand for optimal security and performance will benefit from our more advanced design and consulting services. Our experts have a proven record for success in this space, including the implementation of private and cloud-driven point-to-point copper and fiber optic circuits, including the design of MLPS networks.

Level 3
WOW Internet


Your routing needs may vary according to a number of factors, and our team of network engineers is highly adept at developing customized solutions to meet any of those demands.

We are also experienced in ARIN privately owned IP space management and can offer our support in all operational and technical areas of this service.

Routing Hardware

Realnets offers installation, configuration, routine maintenance and troubleshooting support for all major hardware brands, including Juniper, Cisco, HP and many more. We are also happy to work with you on the configuration of cloud platform routing from AWS and Azures.

Our experience with routing protocols includes:

  • Routing Information Protocols (RIP)
  • Interior Gateway Protocol (IGRP)
  • Enhanced Interior Gateway Routing Protocol (EIGRP)
  • Border Gateway Protocol (BGP)
  • Open Shortest Path First (OSPF)

Firewalls – IDS – IPS

Effective implementation and ongoing management of your firewall is critical to the health of your network and operations of your business. It is an ever-evolving landscape, however, and by partnering with Realnets, you can ensure that your network security stays ahead of the curve.

We take a comprehensive, multi-faceted approach to security by executing powerful Intrusion Detection Systems (IDS) / Intrusion Prevention Systems (IPS). Our managed firewall solutions deliver timely administration, monitoring, and maintenance necessary to keep your assets safe. Our goal is to provide you with a secure environment you can trust.

We work with both open source and paid firewall products, with extensive experience with the following:

  • Shorewall
  • IP Tables
  • Alert Logic
  • Sonicwall
  • Sophos SG
  • Sophos XG
  • NACL
  • Azure
  • Cisco
  • Optical Waterfall

Virtual Private Networks (VPN)

If your organization requires a secure connection between two or more points, there is no better choice than a virtual private network. For the best and safest outcome, though, it should be managed by a partner that understands the complexities involved.

With cross-connecting platforms, sites, and end users comes a complex web of technologies and security considerations. Remote Access VPN and OpenVPN are common requests, and while we work frequently on these projects, our experience spans far beyond this.

Our OpenVPN experience also includes very complex configurations in many cases, and our custom OpenVPN solution development means that your business has access to key and authentication integrations not possible with other solutions.

Other examples of past project requirements in this space include:

  • Site-to-Site VPN projects 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.
  • Layer 2 Tunneling Protocol (L2TP) VoIP projects utilizing protocols such as Cisco’s GRE.
  • Point-to-Point Tunneling Protocol (PPTP) implemented in campus cross-connection projects.
  • Punching through firewalls and other 3rd party networks using Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols.


Switches are the heart of any network, and at Realnets, we’ve worked with every type and speed. Our past projects have run the gamut from full campus rollouts with core + edge design to small business single device scenarios, and you can rest assured that our highly-skilled team has either installed or replaced whatever hardware you have – even products made by brands that no longer exist.

All of our design considerations are centered around the need for built-in redundancy, and engineering tactics that involve Cisco and HP products are among our team’s core competencies.
