Adding a New LAN Group

To create a LAN Group:
Choose Firewall > Advanced Settings > LAN (Local Network) Groups.
Click Add.
Enter the group name; spaces and quotes are not supported. Click Save.
If the group consists of a single IP address, choose Single Address and enter the
address in the Start IP Address field. If the group consists of a range of IP
addresses, choose Address Range and enter the addresses in the Finish IP
Address fields.
Click Save.
Enabling Session Initiation Protocol Application-Level
Gateway (SIP ALG)
SIP ALG can rewrite information within SIP messages (SIP headers and SDP body)
making signaling and audio traffic possible between a client behind Network
Address Translation (NAT) and the SIP endpoint.
To enable SIP ALG:
Choose Firewall > Advanced Settings > SIP ALG.
Check the Enable box to enable SIP ALG support. If disabled, the router will not
allow incoming calls to the UAC (User Agent Client) behind the Cisco RV180/
RV180W.
Click Save.
