I have a CentOS 7 image on VM VirtualBox (bridged Ethernet with static IP) I was trying to set
iptables filter table but I have the following problems:
Whatever I did to open Apache on port 80 doesn't work (instead if I stop iptables service I can load web pages without any problem). I found somewhere that a possible solution could be to write a rule to enable bridge. Is it true? Anyway I can't find any bridge configuration in the machine.
I deleted default rule for port 22 and now I can't even login from SSH, even if I think I restored it.
This is the iptables file:
*filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A INPUT -p tcp -m tcp --dport 10000 -j ACCEPT -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT -A INPUT -p icmp -j ACCEPT -A INPUT -i lo -j ACCEPT -A INPUT -A INPUT -j REJECT --reject-with icmp-host-prohibited -A INPUT -j ACCEPT -A INPUT -p tcp -m tcp --sport 137:139 --dport 137:139 -j ACCEPT -A INPUT -p tcp -m tcp -m multiport --ports 445 -j ACCEPT -A INPUT -p tcp -m tcp --dport 22 -j ACCEPT -A FORWARD -j REJECT --reject-with icmp-host-prohibited COMMIT *mangle :PREROUTING ACCEPT [48:5579] :INPUT ACCEPT [47:5507] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [39:4446] :POSTROUTING ACCEPT [54:7320] COMMIT *nat :PREROUTING ACCEPT [23:1557] :INPUT ACCEPT [0:0] :OUTPUT ACCEPT [7:548] :POSTROUTING ACCEPT [7:548] COMMIT
