How do I activate internet access for the SF-302-08PP

I am trying to activate internet access to this switch. Sometimes i connect to an ethernet port that already has Internet activated. However, this switch does not "detect/accept" internet access? I dont know if i am using the correct terminology. However, I am trying to set up Crestron Xio Cloud and all my devices that are one on the SF-302-08PP need to ensure that thy are connected to the internet.

 

Are there any settings that I can do on my end, through GUI?

This is switch (this is not an Router) - This is not going to perform any NAT, If you have IP address from ISP (Public routable, you can use the IP  on switch  to reach internet.

 

here is basic setup you can do using GUI :

High level your network should like below :

 

ISP---ISP(Modem or router - which can perform Routing and NAT) ---SF3XX Switch--- Lan users.

Hi there,

It sounds like you have multiple VLANs configured on the switch, each available on different switchports on the switch.

I assume that they are all routed on the switch and you have a transit connection to an ISP router, lets call this VLAN1 . When you connect to a switchport on VLAN1 you will have internet access. When you connect to any of the other VLANs you will be routed on the switch and probably sent to the ISP router, but the router will now know how to perform NAT for your source subnet and will discard the traffic.

 

The solution, is to reconfigure the ISP router to NAT these additional VLANs (source subnets). Most ISP routers cannot do this.

 

Is any of the above correct, if not tell us where your setup is different and we can troubleshoot.

 

cheers,

Seb.
