5. DCHP server of VLAN doesn't work (2.0-BETA5 - build Jan 15)

DCHP server of VLAN doesn't work (2.0-BETA5 - build Jan 15)

  • K

    I've created 2 vlans : publicwifi and privatewifi.  Until now everything went well, but i've upgraded today my pfsense 2.0 to the build of jan 15 and it's … broken :-)

    My Lan network's DHCP server works well!

    It's not just that build, I don't think… I'm running the Jan 10 build and the DHCP is intermittent for VLANs on that one.  It seems to work for the first couple of hours, but after that it stops responding to DHCP requests from the VLANs.

    Well, I take that back.  It seems to be a little more complex than that.  I get DHCP response for certain devices, but not others… maybe it has something to do with the syntax of the DHCP request?

    The plot thickens. DHCP behavior is rather… intermittent.  It's not necessarily different devices as I was thinking before, I've now had the same device both function to get a DHCP address, and at a different time be completely unable to acquire one, with no other system changes.  Very odd.

    If you can catch it at a point where it can't renew, capture the traffic, see what's happening.

    I'm running DHCP server on VLANs in multiple locations with no issues.

    My problem is that the DHCP server don't work anymore.  So the solution have to be found there…

    You still need to get a packet capture of the traffic, see if the request is getting to the firewall.

    Do you have any interface that is configured as 'none' assigned?

    I got the snapshot of today (2.0-BETA5 (i386) built on Wed Jan 19 02:10:47 EST 2011) where it isn't fixed yet?

    Looks like that has nothing to do with the version, just that you broke your config. You have VLANs 100 and 200 assigned, but you apparently changed those to VLANs 2 and 3 without properly re-assigning or deleting the interfaces.
