Red Hat Bugzilla – Bug 799143
Firewall prevented dnsmasq from working with virtual bridge network
Last modified: 2012-11-19 06:32:54 EST
Description of problem:
DHCP functionality didn't work with Windows 8 public beta until firewall rule was removed. I thought at first this was an interoperability problem, but removing the last INPUT chain firewall rule (the catchall that sends back an icmp access denied) seems to have fixed the problem.
Version-Release number of selected component (if applicable):
I used the i686 iso from here:
Steps to Reproduce:
1. install into virt
2. boot virt
OS sense out dhcp requests that dnsmasq does not answer.
dnsmasq answering dhcp request, configuring the OS.
I went to re-create the problem & capture the packets with tcpdump -- but this time, it worked. Only thing different now from when it didn't work is firewall changes.
This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.
From the problem description this was a problem with your firewall settings. dnsmasq communication is filtered by firewall settings therefore you should check if there is any firewall rule preventing dnsmasq from receiving/sending packets.
Closing as NOTABUG since this is a firewall settings issue.
If your issue persists, please consider creating a bug for another component (firewall/libvirt/virt-manager).
