Set standards for vpn configuration for Fortigate and Cisco firewalls to guarantee secure remote access by DCANet while minimizing the chance of any kind of security breach. ipsec and ssl vpns.
Configured port forwarding to go through the firewall and to all internal switches for snmp to allow remote monitoring of not only all relevant oid’s on the firewall, but all relevant oid’s on the switches as well. This gave us much faster response times in investigating network problems on remote networks, from DCANet’s office.
Setup a portable odroid network monitoring device that allows remote access into the device while providing network monitoring on all the internals of a client’s network, giving even more depth and understanding to employees at DCANet for a remote client’s internal network, without having to go onsite. Also greatly improved troubleshooting effectiveness.
Identified that having a vlan on the wan interface of a firewall can cause throughput issues on certain firewalls and found the workaround to be installing a switch to take the vlan and put a port on access for the firewall to use.
Change switchport mode to access on cisco switches whose connections terminated on cisco sg800-08 switches so that they could be remotely accesses as sg800-08 does not support vlan access.
Made significant improvements to new employee training.
Updated and maintained a MediaWiki knowledgebase to greatly improve productivity in all departments throughout the company.
Set up Cacti network monitoring live graphs to monitor spikes on core network equipment that are indicative of attacks, and made a separate configuration to provide email notifications for those events.
Prioritized VoIP on firewalls, including dual wan configurations, to remove interference and call drops in all network installations.
Created video tutorials for email access for customers.
Upgraded our Barracuda email spam firewall to provide an additional butt layer of protection and email backup, at no additional cost to DCANet.
Promoted positive and clear communication among engineering and support teams.
Developed several WordPress websites for customers who wanted more modern designs, as well as our own website.
Migrated websites off of our older UNIX and Windows hosting platforms to a newer Linux-based platform.
Upgraded and organized our network monitoring capabilities on Cacti, Nagios, and SmokePing to greatly decrease troubleshooting times.
Created network topography maps for non-standard network designs for easy access on our knowledgebase.
Refined our network alert system and knowledgebase so that it is more thorough and accurate, to allow fast response times and troubleshooting.
Created a table of contents for our knowledgebase to standardize the organization of any further articles and to ensure that all maintained pages are connected.
Translated technical instructions so that anyone could complete the task regardless of experience or time away from the task. This greatly reduced mistakes and allowed a much greater sharing of the daily workload throughout the team, as well as a faster and more thorough learning experience for newer members of the team.
Updated SmokePing’s graphical interface, as well as ping interval and alarm times, to ensure not even minor disruptions are missed anywhere on a network. Multiple threads were used to share the load on the cpu of the server. Also switched the operating system to Arch Linux and implemented FastCGI for greatly decreased load times when opening graphs.
