Trouble with DHCP and VLAN



  • I have trouble with using DHCP server in my VLAN.
    I hope that somebody cab help me with my problem.
    I do not know what im doing wrong, i add here my steps from setting up VLAN.

    • i assign new VLAN with name (student) and tag (2)
    • create new interface OPT1
    • set network IP (192.168.2.0/24) and enable interface OPT1
    • enable DHCP for OPT1
    • add IP range (192.168.2.100-192.168.2.250) in DHCP server
      If I connect my computer with VLAN (tag2) then i get results:
      Dhcp Enabled. . . . . . . . . . . : Yes
      Autoconfiguration Enabled . . . . : Yes
      IP Address. . . . . . . . . . . . : 192.168.2.254
      Subnet Mask . . . . . . . . . . . : 255.255.255.0
      Default Gateway . . . . . . . . . : 192.168.2.0
      DHCP Server . . . . . . . . . . . : 192.168.2.0
      DNS Servers . . . . . . . . . . . : 192.168.2.0
      Everything works with LAN, i get correct gateway, DNS and DHCP server addresses.
      Dhcp Enabled. . . . . . . . . . . : Yes
      Autoconfiguration Enabled . . . . : Yes
      IP Address. . . . . . . . . . . . : 192.168.1.244
      Subnet Mask . . . . . . . . . . . : 255.255.255.0
      Default Gateway . . . . . . . . . : 192.168.1.1
      DHCP Server . . . . . . . . . . . : 192.168.1.1

    Same problem with version 1.0.1, 1.2-BETA.1 and 1.2-BETA.2
    Did anybody can help me?
    Sorry for my english.
    Thanks



  • You need to use a valid IP on the OPT interface, not the network address. i.e. it needs to be 192.168.2.1/24, not 2.0 as that's the network address and not a usable IP. It looks like it's working as would be expected, if you just use a legit IP you should be fine.



  • It helps,
    Thank you very mutch!  :)
