The goal for this project is to replace dd-wrt routers running on the clients' users.

I deployed pfsense as a replacement to the dd-wrt router and it runs inside vmware esxi as a virtual appliance.

The network then becomes more manageable using this pfsense router because of its features where you can specify rules, traffic shaping and graph reports, vlans and many more.

$This project involves setup of unifi wireless controller and connecting all unifi APs automatically by adding static dns record for the controller where all APs will try to connect to the controller by its default hostname \"unifi\".$

This Microsoft Exchange project was implemented because the clients wants to their cloud hosted mail server to be transferred to an on-premise mail server running Microsoft Exchange 2010. Task includes setting up the exchange server on Windows Server 2012, registering ssl certificate to Godaddy for external access of the Exchange, changing dns records(A record, MX) to point to the new on-premise exchange server.

I have setup a multisite wan optimization for a Satellite network.

Each site has 4mbps on the wan link but with traffic deduplication using Silverpeak, we saved about 20-25% bandwidth thus improving the performance of the Wan link.

I setup multiple servers that we use for our ISP Billing and Management.
SequreISP is a great ISP system that has a lot of features for client management as well as overall internet control.

With SequreISP, you can create internet plans for different clients. It could be a residential plan or business plan depending on the clients' needs.

Traffic graphs are very useful. You can view per client traffic or overall internet traffic that caters all the clients.

It has transparent proxy(SuperCache) that is used for fast page browsing through web caching.

And much more features....

This project is about planning and deploying Microsoft Exchange 2013 in 3 remote offices.

The setup involves creating a VPN tunnel between the 3 remote offices to be connected as a local network for Active Directory purposes.

The 3 remote offices connected via VPN are logically separated using the AD Sites and Services.

One of the remote offices has the internet-facing server that accepts external emails and relay emails to the correct destination office.

MX and DNS records are in place through a Public Domain hosting company.
