Vyatta Simple Firewall Setup
I decided to setup a simple firewall on my Vyatta VM router to block pings from another VM Host (Ubuntu 12.04). The network is entirely in the range 192.168.0.100/24. The Ubuntu Host IP is 192.168. 192.168.0.111
The Vyatta interface IP is 192.168.0.108
Ping between them is working prior to setting up firewall and gives destination port unreachable as soon as firewall is enabled via commit.
The firewall configuration is as below:
The configuration steps are simple and given below:
and then we need to apply the firewall to an interface which in this case is eth0.
After the above configurations are in place enter commit to apply them and ping will stop working.
We can also see the statistics in firewall section changing:
and also by name the firewall:
and also show firewall name *** statistics :
