Setup firewall rules vyatta

These can be packets that traverse the Vyatta system or that originated on the system. You can apply one out packet filter. If you apply the instance as local, the firewall filters packets that are destined for the Vyatta system. One firewall instance can be applied as a local packet filter. You can apply a total of three firewall instances to an interface: one instance as an in filter, one instance as an out filter, and one instance as a local filter.

The following example shows a firewall rule set applied on a public interface of the Vyatta system. This rule set performs the following actions:. Sets recommended global rules to be applied to all firewall interfaces in this case, the public interface.

Any other interfaces with a firewall configuration will also inherit this configuration. Set the recommended global rules that will apply to all firewall protected interfaces. Anything global can be changed within the interface-specific firewall rule. After you have set up your firewall to protect your Vyatta VM against attacks, you can configure custom rules from the default configuration. The following example shows a series of custom rules that allow you to enable site-to-site VPN traffic to your Vyatta VM.

I understand clearly the examples, and the output. I need to try it, and see what happens. The only difference that i can see, is that im using a zone firewall,i have rules set , applying from a zone to another zone, and the zone have a of interfaces that belongs to it. Maybe i cant monitor firewall rules because im using Zone-Based firewall?

Right now, i solve situations whit conntrack and tcpdump, but i need to be very creative to use it :- and many many times , even when i see the traffic , i take my time to understand it. Anyway, thank you. TravelingPacket — A blog of network musings.

That would be killer.

The issue I am having is getting it to apply the firewall rules to my interface, which is pppoe0. In the config there is a space. I will mess around it for a bit again, and see if I can get it to work. I have to convert my notes to the new config format still. I have some of the main commands working, but not all.

I have a separate guest network here and I never plug in an infected system until I'm pretty sure that I have it already cleaned up. Connecting the cleaned system to the internet is typically my last step, I will run an online AV and sometimes Secunia to see if there are any applications that need updating, and then update them. To continue this discussion, please ask a new question. Which of the following retains the information it's storing when the system power is turned off?
