Hi.
in my office i do have a cisco 877 to get access to the internet where i do have a static IP address. The LAN has IP 192.168.0.0/24 with 192.168.0.1 to be the router.
in my LAN i do have a voip server which is on 192.168.0.50
all of the PCs have access to the voip server with softphones.
i would like to filter access of the voip server only for local access, in order to avoid high charges.
any ideas on what config fo i have to setup?
