Having an issue with two SG250-26HP switches. When I assign VLAN 1 a static IP address, I lose the GUI and ability to ping it from outside the LAN. If I revert back to DHCP, the GUI comes back and I can again ping from outside. Is there a security or other setting that would cause this? Also, it seems if I change from DHCP to Static IP, I lose my native VLAN configuration on other trunk ports that are not set to VLAN1. Any assistance is greatly appreciated.
