Hello,
I have an interesting problem where 90% of my network works just fine but a small part of it I cannot make to work right. I have a bunch of VLANs all controlled by the CRS and they all route out through my PFSense box, but (and I cannot change the physical topology) VLAN 3 has the DHCP Server on the PFsense box, and tere is a bridge on the PFSense box between two ports as there is a mission critical machine that needs to connect directly to PFsense (security blah blah blah who cares) and then the other part of the bridge connects to the CRS and then onto another 20 or so devices. These need to be strictly on the same subnet as each other. Like so:
I cannot make this work. I have been at it for days now. the problem is obviously having VLAN 3 (which is the uplink port on the CRS (they are physically different cables from the other machines I have) on the same subnet as VLAN 4 which is the VLAN on which all the devices are.
How do I do this? I did have it working if I used a separate bridge and put VLAN 3 and 4 in that bridge, but then the uplink port is a slave interface and only keeps its IP until renewal and then it all falls apart.
Thx
Julian
