Giving my 2nd vlan access to the internet.

JoeF1 · 5 Aug 2013 at 12:01

Hey

I have a little room of computers that are on their own network running back to a Dlink DGS 1024D switch which is not interfacing.

We are upgrading all their adobe suites which will now be ran from the cloud so have to be internet facing. I cant just plug them into our main admin network because they will not see the servers any more. Usually i would add a 2nd network card to get around this (which i am going to do) although they have a iMac. Am i having a blonde moment and missing something simple here. How can i get the internet to that switch? is it as simple as running a cross over cable from the Dlink switch to the 3com switch which is internet facing?

(I cannot change the IPs this is why i have'nt just changed the ports around).

Thanks.

Where does a vlan fit into this? It sounds like a completely seperate physical network.

Sorry it is a physical network. Have no idea why i put vlan in the title. Mods can you take vlan out for me.

Just so no one gets confused - i have 1 switch (A) which connects Network 1. Another switch which with internet facing (switch B).

(A) At the moment is not online.
(B) Is the main network which has the AD etc on.

Is their a way to get (A) to connect to (B) without changing IPs?

Cannot change IPs as (A) has its own servers on.

Thanks.

It might be overcomplicating things, but you could connect the two networks together with a normal cable router. WAN side connected to the main network.

I cant add any more routers. I can only work with what i have got. I dont think this can be done without changing the IP ranges for every machine on the mini network.

Thanks

The only way to link two networks is with a router. If you use a switch it becomes one network. Yes there are exceptions such as L3 switching and VLANs but let's not complicate things.

Im getting confused we have a few vlans down there which hopefully i can find a diagram off so i know the port ranges. I think it will be best to bite the bullet and add it to our production/factory* vlan and change the ips on the machines. Future proofing and all.

Surely there was a reason it was a totally separate LAN before? For running your own DHCP, management etc? The best way to provide internet access with minimal disruption is going to be a router.
