If remote clients are allowed to access only local corporate resources and the Internet access is restricted on the VPN server, a remote user won’t be able access external websites and other Internet resources from their computer. It means that all traffic from your computer is sent through a VPN tunnel. If you want to prevent remote access as well remove -state NEW from those rules.When creating a new VPN connection in Windows (all version), the option Use default gateway on remote network is enabled by default. By checking for NEW, we’re preventing those devices from initiating outbound connections, but not preventing them from being accessed remotely and sending replies through the WAN (at least when the VPN is down). The state of the connection checked for is NEW.In contrast, REJECT causes the client to quit IMMEDIATELY. ![]() DROP doesn’t respond and requires the client to timeout, which can be annoying for users. It uses REJECT instead of DROP since the former it’s a bit friendlier than the latter.Iptables -I FORWARD -p tcp -s 192.168.1.128/25 -o $(nvram get wan_iface) -m state -state NEW -j REJECT -reject-with tcp-reset Now for the second part of the problem, which is denying WAN access to devices that should be on VPN when the VPN is off/fails can be done by entering the following commands in the Save Firewall section: iptables -I FORWARD -s 192.168.1.128/25 -o $(nvram get wan_iface) -m state -state NEW -j REJECT -reject-with icmp-host-prohibited The devices that should not go thru the VPN should get a static IP 127 thru the VPN). ![]()
