Router on a Stick



  • I currently have pfSense 2.3.3 installed which is connected to a Cisco SG300 in layer 2 mode. On pfSense I have 2 VLAN interfaces 99 and 100 defined on the LAN interface. On the Cisco SG300 the trunk port connected to pfSense has VLAN99 and 100 Tagged and VLAN 1 Untagged. Everything works on VLAN 99 and 100 but the IP address of the Cisco SG300 is the default 192.168.1.254 ip address. I am unable to reach that IP if I put myself in VLAN 1 on the SG300. Not sure how I can get this to work. Any help would be greatly appreciated. Thanks!

    VLAN 99 = 192.168.99.1/24
    VLAN 100 = 192.168.100.1/24



  • You neglected to tell us you lan subnet… is it 192.168.1.x/24?



  • The LAN interface does not have an IP address.  I have workstations on both VLAN 99 and 100. I am just unable to reach the Cisco SG300 to manage it. I tried changing the default IP of the SG300 to 192.168.99.2 and changed the management VLAN to 99 but no cigar.



  • SG300#
    SG300#configure
    SG300(config)#vlan database
    SG300(config-vlan)#default-vlan vlan 99
    New Default VLAN ID will be active after save configuration and reboot device.
    SG300(config-vlan)#exit
    SG300(config)#interface vlan 99
    SG300(config-if)#ip address 192.168.99.2 255.255.255.0 {gateway address}
    SG300(config-if)#end
    SG300#wr

    reboot (with "reload")
