OK, so you have connectivity between everything on the switch, yes?

Which device holds the default gateway for your network?

Can you ping the default gateway from the server?

Have you created a rule that allows traffic to and from this new IP address on the hardware firewall?

Can you ping the new IP from the firewall?

If yes, can you in the web GUI (on the ISP router) see a MAC entry for all attached devices?
