Hi everyone,
I am doing an experiment with my mini-server running
OVS
ryu 4.7
mininet
In mininet, i used below command to create a network topology which has one
switch and 2 hosts.
sudo mn --topo single,3 --mac --switch ovsk --controller remote -x
and then i changed the ip of each host as below
h1: 10.0.0.1/28
h2: 10.0.0.17/28
I want to implement the firewall into my network topology by running
rest_firewall.py through ryu-manager. After running rest_firewall.py on ryu
controller, I execute these command:
# Enable firewall on switch dpid=1
$ curl -X PUT http://localhost:8080/firewall/module/enable/0000000000000001
# Install rules for ICMP connectivity.
$ curl -X POST -d '{"nw_src": "10.0.0.0/28", "nw_dst": "10.0.0.16/28",
"nw_proto": "ICMP"}' http://localhost:8080/firewall/rules/0000000000000001
$ curl -X POST -d '{"nw_src": "10.0.0.16/28", "nw_dst": "10.0.0.1/28",
"nw_proto": "ICMP"}' http://localhost:8080/firewall/rules/0000000000000001
Then i tried to ping from h1 to h2 from mininet but i got an error message
which said "network couldn't be reached". It seems like there is no route
to each network. So my question are:
1. Does rest_firewall.py work across the networks ?
2. If it works, How to set the route to each network ?
Best Regards,
Hong Panha
