750G help needed Please

Hello there from a total newbie!
Please assist me with setting up my 750G I have tried and Google’d a lot but I just don’t get it right.

I have a network at my remote office that is fully setup and working, ip range 172.27.18.0/24 subnet 255.255.255.0 (inherited from predecessor and cant be changed). I want to create two more ranges 172.27.19/24 and 172.27.20/24. Setting this up and dhcp for each has been done but i need to access any pc from any of the ranges and they must be able to see the server on the 18 range.

Hi Gabriell,

Are you able to post an export of your config and possibly a network diagram of what you’ve got configured so far?
This will help us to see what exactly you’re trying to achieve and if there’s any misunderstandings in the way you’ve got it currently set up.
