<![CDATA[Help with trunking from Cisco switch (can get DHCP, not able to ping out)]]>Hello,

I'm attempting to setup a network with 6 VLANs on a Cisco 3560G connected to a pfSense box. VLANs are VLAN101, VLAN201, VLAN301, etc. I have followed the tutorial at http://networktechnical.blogspot.com/2007/04/pfsense-how-to-setup-vlans.html and DHCP successfully works for each VLAN when connecting via the switch. However, from the switch I cannot ping the gateway address for the VLAN (the address on the pfSense box).

For example:

VLAN101 is defined on the pfSense box to have an IP of 10.2.1.1/26. The DHCP range for that interface is 10.2.1.30 - 10.2.1.60. When I plug a machine into a port on the switch, it receives a DHCP address (10.2.1.30) and can ping the VLAN101 interface on the switch at 10.2.1.62. However, it cannot ping the VLAN interface on the pfSense box at 10.2.1.1.

I have made sure that I have a firewall rule for allow any traffic for VLAN101 ("*" across the board on the rule page).

The configuration for my trunk port on the switch is:

interface GigabitEthernet0/49
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 101,201,301,401,501,601
switchport mode trunk

and the port I'm plugging the machine into is:

interface GigabitEthernet0/13
switchport access vlan 101
switchport mode access
spanning-tree portfast

Any thoughts as to where I should go next in troubleshooting this?

Thanks in advance!

Resetting states seems to have done the trick.

(See Diagnostics -> States click on Reset States, read and click the Reset button.)
