Baystack 450 VLANS connected with x-over cable

[putney]

I have two VLANS on a 450 that I need to connect with a cross-over cable. each of the vlans are for the same subnet, but they are being fed from different domains of a firewall attached to a trunk port. It appears that the MAC addresses for both ports are the same so there appears to be a traffic issue across the cable. Sometimes I get a single ping, but most of the time I just get timeouts. I've disabled spanning tree on the ports so they don't shut down.

I'm looking for suggestion on how to pass traffic across the VLANS. The only way for the firewall to have the same address on different vlans is to put the valns on differnt domains. The firewall is a Fortinet, which does a great job, but it does have some growing pains.

Should just be a matter of configuring the ports that the crossover cable connects to as tagged trunk ports, then make sure that those ports are members of both VLANs. You would then assign the VLAN to the ports on the switches as required, make sure the port is configured as untagged, and set your PVID to the appropriate VLAN ID.
