I have a network of a couple of SG200, SG220, SG250 switches and I need to replace my firewall which is my default gateway for my network and a couple of VLAN's configured on the switches and on the Firewall
When I replace my firewall which is configured on the same IP and has a copy of the configuration from the old unit, everything on the VLAN's stops working, I have tried a reboot of the switches after talking to my firewall vendor but still no go and they also checked my firewall config and everything is good on that side. When I plug back the original gateway and reboot the switches everything works back like a charm.I tried to plug the wires to the same port to see if it would be a port configuration but still the same problem.
Is there a table in the switches that would keep the MAC address of the firewall for routing ? or anyone has another idea ?
Thanks

- You may want to clear the arp-table on the switches.

You can clear the content of the switch ARP table using the clear arp-switch command. Details on:
