2.5 latest update issue
Everything was working fine until I when an update PFsense 2.5 to the latest update. I lost internet connection, DHCP was not giving IP address on Vlans. I was able to login into LAN with static IP. I tried to restore a backup but it didn't fixed the issue. I reset everything back to factory and I am not running Vlans at the moment. DHCP running fine without Vlans but a soon I create them DHCP won't work. It is showing that service is UP but not working. Any one with this problems with 2.5?. I'm putting out there to see if any one else is having this issue?
Need a lot more detail than this. VLANs are working perfectly here, so if there is a problem, it must be something specific to your setup.
What version did you upgrade from, 2.4.5 or an earlier 2.5.0 snapshot?
What kind of environment? Bare metal (if so, what hardware?), Hypervisor/VM (If so, which one / version)?
What type of NICs / NIC driver does it use?
You arent alone.
I think it may be related to https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=240818
If you down/up the parent interface (em1 in my case) things will work.
