Networking

Hi guys,

I am relatively new to the whole networking industry and i have a bit of an issue with a few things on our current business network which is an academy.

Let me start off where i was left for dead, we previously had two network segments 192.168.150.x and a 192.168.4.x network, where the .4 network was responsible for providing VoIP services to the IP phones we had and the gateway for this network segment was on the same network. This was a PABX server and was statically routed to our PFSense Firewall which is on the .150 network. We also had two managed switches which was having an ip addressing of 192.168.4.2 and 192.168.4.3. These two switches were feeding the office and the campus segments with internet access and were all able to contact the domain. Everything was hunky dory till the people who installed all these services decided to up and leave and take all this infrastructure with them.

We then had to rebuild the network, office users needed to access network drives on the .4 network and the campus computers needed to be on the .150 network for restricted access to certain sites as the firewall is on this network but still able to access the internet fairly quickly. I believe the previous configurations had vlans configured to be able to have two network segments. We have an ADSL/VDSL connection from Telkom and an analogue PBX server, we configured the router to have the .4 network just like before and we bought two managed switches, a POE switch and an unmanaged switch. There are quite a few cables running from switches in and around the campus, tracking them are a mission, but i have managed to give access to the users on the .4 network to the network drives, however the campus computers are getting internet access but are not able to access the internet though they are on our domain. The computers give me an error message saying there are no DNS records. I have checked the Domain Controller and tried to manage the DNS server and the DHCP server with scopes but to no avail.

Can someone please advise me on how to give these campus machines internet access properly.

I would greatly appreciate any help offered.

Re: network

It seems time for the academy to:
(1) hire a professional and capable network company to fix their infrastructure
(2) offer the it staff the courses and education they need to manage the network after it's fixed, unless they prefer to outsource not only the installation but the managing also.

I don't understand how people can take an infrastructure with them and get away with it, but that doesn't matter at the moment.

At some point

We have to get better IT staff or hire the job out.
