    Are you running the switch in L3 mode? if it is, does it have its own network?

    Is the issue only with the switch?

    Yes, the switch is acting as a router. All the devices behind the switch can talk to each other but when the switch WAN interface is set to DHCP (Pull an IP from the Gold Pro) im getting 0.0.0.0 and the internet is down due to traffic can not route pass the switch; if i set the WAN port to static and assigned an IP within the Gold Pro network then i can route pass the Gold Pro and surf the internet. Unfortunately, the switch is the only device that support LAG other than the ISP router (which sits in the other side of the Gold Pro). Like i said in my previous post i tested the ability of the switch to pull an IP by bypassing the Gold Pro and connecting the switch straight into the ISP router and the switch pulled an IP, no issues...

    What is this switch model? and I assume it is just a full router? Do you have any extra DHCP settings on the switch? (WAN port)

    Are you operating the XGS2220 in L3 mode or L2? meaning, ensure its DHCP is off, and not doing any DHCP forwarding
