Multiple subnets internet access

Question

I have a EdgeMax Router X and I got the basic to work. The subnet for the default is 192.168.178.1

My wifi access points have the option for guest networks. Those however are on a seperate subnet 192.168.179.1

This didn't seem like a problem to me but the 179 subnet doesn't seem to be getting internet access.

Who should I give the 179 subnet internet access? In doing so will it also be able to communicate with the 178?

I tried to add a manual ip to the 'switch0' interface in my router (so both 178 and 179 are configured there) but it doesn't seem to work.

Thanks in advance

Edit:

Please post the configuration of your router. you will likely have to configure VLAN trunking on your router for the guest network. — Ron Trunk, Jan 6, 2017 at 12:29
Not sure how to post any. It hasn't got much configuration yet. Basically only a DHCP for 192.168.178.0/24 and a switch interface. — John, Jan 6, 2017 at 13:33
You can edit your post to insert it. Use the "preformatted" text option. — Ron Trunk, Jan 6, 2017 at 13:38
All of it. especially the interface and vlan configurations. We also need to know more about your access point configuration. — Ron Trunk, Jan 6, 2017 at 13:41

The details of what you need to do are too involved for a post here, but these are the high level steps:

Create two VLANs on your switch- one for users and one for guests
Create a trunk port on the link between your switch and router to tag the VLANs
Create subinterfaces on your router-- one for each VLAN: 178 and 179
Create a new DHCP scope for your guest network
Apply an access control list on your router to block guests from reacing your internal network.
