<![CDATA[Multi-LAN using VLAN's and Managed Switches, pfSense crashing.]]>I'm running pfSense 2.0. My configuration is as follows, I have my LAN link connected to some managed switches and have create a VLAN for each department in the building. I then set all ports that belonged to a specific department to untagged and the correct people were getting the correct IP's for their given departments. The configuration seems work good but crashes after about 6 hours and the only way to fix it is to reboot pfsense. When it crashes I loose all access to the box over WAN as well as LAN.

WAN (DHCP)
LAN (VLAN1) 192.168.1.1
LAN2 (VLAN2) 192.168.2.1
LAN3 (VLAN3) 192.168.3.1
LAN4 (VLAN4) 192.168.4.1
MGMT (VLAN4093) 10.10.10.1

I have not yet had a chance to look at the logs as the box is in the process of being rebooted. Has anyone had issues with this type of setup?

@dreamslacker
Disable NAT Reflection for 1:1 NAT - DISABLED
Disable NAT Reflection for port forwards - DISABLED
Firewall Maximum Table Entries - DEFAULT (Left it Blank)
Firewall Maximum States - DEFAULT (Left it Blank)

EDIT: Now that I am onsite here I found that the old router (connected to the same ISP) still had the static IP settings of the new router. Switched it to DHCP and I think our issue may have been resolved.

I can no longer log into it via SSH, HTTP (WAN or LAN). Its sitting in a cabinet and I do not have a monitor connected to it at the moment. I'm going onsite tomorrow morning and will be taking a closer look. This is the first setup of this kind that I've done. I know that some of the old routers were disconnected although its possible that someone reconnected one and its feeding DHCP back into the network and I know that with standard routers it can cause similar symptoms. I'm hoping that's all it is as it will be very simple to find/fix.
