Hi all,
I have a cust who shares the building as about 10 other companies and they are on the same switch and router, hence they are able to see the other machines on the network which is not good.
So what I thought we could do is either use a software firewall or software vlan on each of the machines so they can see what they need to but not access anything else.
The only problem I have come across is most software firewalls don't seem to be able to specify by mac address, ip address is not really feasible because they are using dhcp and I don't have access to the router.
Or is there some software vlan that I can install to each machine, I am trying to get around spending money on a new switch.
