Advanced > Firewall Settings > Custom Services
Custom services can be defined to a dd to the list of services available during firewall
rule configuration. While common services have known TCP/UDP/ICMP ports for
traffic, many custom or uncommon applications exist in the LAN or WAN. In the
custom service configuration menu you can define a range of ports and identify the
traffic type (TCP/UDP/ICMP) for this service. Once defined, the new service will
appear in the services list of the firewall rules configuration menu.
