I recently installed Linux Mint with following information:
DISTRIB_ID=LinuxMint DISTRIB_RELEASE=18.3 DISTRIB_CODENAME=sylvia DISTRIB_DESCRIPTION="Linux Mint 18.3 Sylvia" NAME="Linux Mint"
And I noticed that it can't open some particular websites (it stuck at
waiting for www.domainname.etc ....). Then I tested with ping and I noticed that it can easily ping to those websites. I tested the Open DNS and tweaking the DNS settings but it didn't work. Does anyone know what can cause such problem? I also checked many links but none of them were useful.
Regarding the firewall problems here is the content of
sudo iptables -L -n Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination
