    Hi all,

    We are running FOG v0.32, running on full cisco network.

    [LIST=1]
    []We used to be able to multicast across VLANs, then suddenly we were not able to.
    [
    ]We can multicast on the same VLAN that the FOG server resides on just fine.
    []When we try to multicast across VLANs the machines will pxeboot to fog, join the queue then sit at Please Wait and never start.
    [
    ]Unicasting across VLANs works just fine.
    [*]The multicast log shows nothing of significance.
    [/LIST]
    No configurations changed on the FOG box; but suddenly we lost the ability to multicast across VLANs. The only network changes made that[I] could[/I] have affected operation were the installation of a Fortinet Fortigate, and a few routing changes to our Cisco Nexus 7k.

    When I run the steps listed here: [url]http://fogproject.org/wiki/index.php?title=Troubleshooting_a_multicast[/url] I can get 3 machines to multicast across VLANs.

    Our FOG server has only one NIC (eth0). We only have one storage node (on the FOG server itself.)

    Here is our hosts file

    [CODE]

    127.0.0.1 localhost

    172.16.203.2 FOGserver

    The following lines are desirable for IPv6 capable hosts

    ::1 localhost ip6-localhost ip6-loopback
    fe00::0 ip6-localnet
    ff00::0 ip6-mcastprefix
    ff02::1 ip6-allnodes
    ff02::2 ip6-allrouters
    ff02::3 ip6-allhosts

    [/CODE]

    [B]FYI: the db user and password used in /opt/fog/service/etc/config.php and /var/www/fog/commons/config.php are the same.[/B]

    Here is our /var/www/fog/commons/config.php

      SOLVED: Changing the multicast queue size from 10 to an arbitrary number, then back to 10 corrected the issue.
