networking - Firewall connected to a switch using 2 ports (LAN & DMZ), but switch management talks on DMZ port

Someone let me know if I'm off track here.



I'm setting up a firewall with 3 ports configured (WAN, LAN, and DMZ). The LAN and DMZ ports both connect to the same switch, on which I will configure a VLAN to segregate LAN and DMZ traffic.



I've got a bit of an issue in that the switch insists on its web-management interface talking to the firewall over the port designated to the DMZ (for the moment I've reconfigured that port to be a LAN so I can get on the switch to configure it).



If I've done everything correctly to this point, can someone point me in the right direction on forcing the switch to communicate it's management data over another physical port?



The firewall packet captures clearly showed the traffic going to it on X0 port and being received to the X2 port by default.
