Path: Security > Firewall > Custom Services
Custom services can be dened to add to the list of services available during rewall rule conguration. While
common services have known TCP/UDP/ICMP ports for trac, many custom or uncommon applications exist
in the LAN or WAN. In the custom service conguration menu you can dene a range of ports and identify the
trac type (TCP/UDP/ICMP) for this service. Once dened, the new service will appear in the services list of the
rewall rules conguration menu.
To add, delete, or edit a custom service:
1. Click Security > Firewall > Custom Services.
2. Right-click an entry and select either Edit or Delete. To add a new schedule, click Add New Custom
Service.
