3 VM in GNS3, one switch,

two act as primary and secondary web server and run pjango

python manage.py runserver --noreload 192.168.1.2:80
python manage.py runserver --noreload 192.168.1.3:80

i use 192.168.1.8 as third computer to access 192.168.1.9 which act as floating ip, however third computer can not ping 192.168.1.9 or use web browser to access the web

conf t
int vlan 10
ip address 192.168.1.1 255.255.255.0
