[SOLVED] Multiple VLAN Issues

calix0817

I have pfSense 2.1.5 (amd64) running in VMWare ESXi 5.5 connected to a Cisco SG200-26 switch. The following 3 VLANs are currently defined in pfSense:

Server Network - VLAN 100 - 10.52.0.0/23
Management Network - VLAN 112 - 10.52.12.0/23
Guest Network - VLAN 203 - 192.168.203.0/24

DHCP is enabled on all VLANs and the address for pfSense on each VLAN is x.x.x.1. Here comes the fun part:

Server Network:

Can get DHCP Address
Can access internet
Can ping anything on Server Network
Can ping anything on Guest Network
Can't ping anything on Management Network

Management Network:

Can get DHCP Address
Can access internet
Can't ping gateway (pfSense) at 10.52.12.1
Can ping everything else on Management Network
Can't ping anything on Server Network
Can ping anything on the Guest Network

Guest Network:

Can get DHCP Address
Can access internet
Can ping anything on any Network

There is only 1 firewall rule on each network that is allowing all traffic. I am expecting all configured VLANs to function like the Guest Network with the current configuration. What could be happening to cause the Server and Management VLANs to not talk to each other? The only devices on the Management network are: pfSense (10.52.12.1), the switch (10.52.12.6), and a laptop for testing the VLAN.

Are you sure DHCP is assigning a 23-bit netmask to your clients where necessary?

calix0817

Yes, I just double checked. The clients in both the Server and Management Networks are getting a /23 netmask.

Well, double check everything. This stuff just works.

Start posting interface and firewall rule screen shots to get more eyes on what you're doing.

I found out the issue. An ipsec subnet was overlapping with the new VLANs causing a routing issue.

Stupid me for setting up the VPN before finishing the VLAN configurations. (And stupid parent company for forcing us to these new ip schemes and demanding a VPN while still using 10.0.0.0/8)

Marking as solved. Thanks.

@calix0817:

10.0.0.0/8

Seems I've heard that somewhere before. 10.0.0.0/8 is pure evil.

Glad you found it.
