Hi Rafael, Good day to you, and thank you for your reply.
Can't find anything wrong on dnsmasq.log / daemon.log, just some log entries related to DHCP, nothing on DNS. I masked the IP addresses since they are public. === Jul 20 16:21:51 r-2606-VM dnsmasq[3519]: DHCPDISCOVER(eth0) X.X.X.X 06:62:a8:01:13:37 Jul 20 16:21:51 r-2606-VM dnsmasq[3519]: DHCPOFFER(eth0) X.X.X.X 06:62:a8:01:13:37 Jul 20 16:21:51 r-2606-VM dnsmasq[3519]: DHCPREQUEST(eth0) X.X.X.X 06:62:a8:01:13:37 Jul 20 16:21:51 r-2606-VM dnsmasq[3519]: DHCPACK(eth0) X.X.X.X 06:62:a8:01:13:37 yyyyyy Jul 20 16:23:53 r-2606-VM dnsmasq[3519]: DHCPINFORM(eth0) X.X.X.X 06:43:4a:01:12:65 Jul 20 16:23:53 r-2606-VM dnsmasq[3519]: DHCPACK(eth0) X.X.X.X 06:43:4a:01:12:65 zzzzzz === Yes, the guest VMs are having difficulties resolving domains into IP addresses because of the problem on the VR's DNS server. $ host www.google.com X.X.X.X (where X.X.X.X is the IP address of the VR) ;; connection timed out; no servers could be reached However, from within the VR, I am able to resolve domains just fine. Any advise where can I start troubleshooting this? Looking forward to your reply, thank you. Cheers.
