Current Comtun 4.0 or later release has a built-in firewall. You can adjust the security level under the firewall tab. We strongly recommend you to upgrade to the latest version in order to completely secure your gateway host and the local network. The previous Comtun/Comsocks version is a basic network firewall through NAT or proxy function (not configurable), it can protect your LAN if the gateway itself is secure and Comsocks has no inbound port mappings. In order to protect your gateway better under the previous Comsocks (v3.08(a) and below) a special care must be taken to protect the gateway.
