University Portal is not visible(accessible) by users on different VLAN?

Question

I am web developer in a company. Currently we developed a web portal which will be used inside the campus only.(Intranet). The problem is that users on different VLAN are not able see the portal. it is not accessible to them. Can anyone say something on this?please?

Answer 1

Well it appears to me you have two choices.

Open the router up to allow the portal to be "Internet" viewable. you need to port forward port 80 for http, port 21 for ftp, port 443 for https etc. to the local portal server private address. Then those outside your LAN can see the portal.

Or you need to setup a VPN which will issue "Local" lan addresses when "outside" users want to connect to the local network to view the INTRANET. A VPN creates a new "tunnel" to your local system and the remote users become part of the local network. It is more secure than an open internet connection.

Now for the third possibility now that I see you said VLAN meaning all have local addresses and not WAN addressing. Those vlan users are indeed on the inside of the same system just on different ip's and subnets.
Your portal host is on 192.168.1.10 for instance and the other vlans are 192.168.2.x you can change the subnet mask of your network to allow all your local addresses to communicate internally. The subnet has to be big enough to allow ALL the addresses with all the lans. Just visit http://www.learntosubnet.com for a full explanation.
