Re: I want to install a firewall on centOS 6

Hello, give me this task for me to perform, with those rules to implement, and I will have to do it badly or well, with the help here of the forum or without help. I won't resort to any professional help, because I can't. I always thought that exposing the task / problem could help me, I was really ...

Re: I want to install a firewall on centOS 6

I ran the command: sudo / sbin / chkconfig --list iptables, and suggested the following:
iptables 0: no 1: no 2: yes 3: yes 4: yes 5: yes 6: no.
What does it mean?

Re: I want to install a firewall on centOS 6

Hello, I know I had not defined any iptables rules yet. That's why I was asking for help. My server is not yet physically connected to the network (abroad), so no problem. I will only connect it when I have all the rules and routes defined. I already defined some rules today, and when I ran the #ipt...

Re: I want to install a firewall on centOS 6

Hello, I already know that SSH is a network protocol and is used to manage servers remotely, I can then use OpenSSH or Putty. I ran the command on my server: # iptables -S, and the result was as follows: -P INPUT ACCEPT -P FORWARD ACCEPT -P OUTPUT ACCEPT. I also ran the #ip ro command to see the def...

Re: I want to install a firewall on centOS 6

I said xpto.local at the example level. My machine's hostname is BMFW and the management console should respond to the internal domain which is: cm-olb.local.
How can I use ssh to manage my firewall?

Re: I want to install a firewall on centOS 6

Good afternoon. I have no program to manage the firewall, I was thinking of creating the rules through iptables. I have a server with CentOS 6 installed and due to the old hardware it does not support newer CentOS versions. But me, I have installed CentOS (command line, not the desktop version), and...

Re: I want to install a firewall on centOS 6

Good morning, I still can not list the rules, because I have not defined them, because I have some doubts. The server where I will implement the firewall rules will serve as a print server. My server has 2 network cards, which are: RedeA: 192.168.4.0/27, and RedeB: 192.168.250.0/24. The eth0 card's ...

Re: I want to install a firewall on centOS 6

I will use iptables to configure my firewall (this will be a print server), firewall rules should only allow RedeB source traffic (192.168.250.0/24) to ip 192.168.1.209 only. (All ports in a 1st phase send the necessary ports via this route). Management of the firewall should only be possible from n...

Re: I want to install a firewall on centOS 6

I want / need to install open source untangle firewall software or another equivalent (32-bit) solution, because I need to define a rule set [this server will work as a print server]. On this server I installed CentOS 6 (also 32 bit).
