I installed RHEL 7 using server with GUI with no added option on my local virtualbox, but I cannot get Firefox connected to the Internet.

  1. I checked /etc/resolv.conf contains nameserver setting
  2. I can ping other servers, such as
  3. I open the firewall config GUI, I can see connected is at the left corner, I added http, https and 80, 443, 8080 and 8443 in public zone, and set interface to use public zone

Firefox cannot get connected, and I can't curl either. Could some RHEL experts explain what I am missing?

  • Can you ping www.google.com ? – Konstantinos Feb 9 '15 at 23:20
  • Can you ping your default gateway/router/internal network from virtualbox?Did you use static ip or DHCP? Temporary disable firewall and try to connect to internet. – supriady Jan 3 '17 at 3:22

I will answer my own question

I was using VirtualBox 4.3.14 on Windows host, after upgraded to latest 4.3.22 everything start working. Without any RHEL config changes.


Despite having checked /etc/resolv.conf you must make sure that DNS is actually working. Try to make a simple request such as dig www.google.com and see whether you get a response.

If that works you can try to manually open a connection with telnet like this:

telnet www.google.com 80
