Our ISP gave us two IP addresses, one is a 72.xxx.xxx.xxx the other is 216.xxx.xxx.xxx. The 72 number is what we use for internet access, the 216 number is suppose to find the computer with a specific mac address and assign the 216 number. When go to internet ask what my ip, it shows the 72 number, which is our main number, what I need however is for the remote sip server to see the 216 number, for the one computer. Do I have to setup the 216 number as the main number to have the sip server see this computer, and clone the mac address or can I do some kind of port forwarding that would work or maybe have to do port forwarding with the 72 number? Using a SA520. Any help would be appriciated. ... View more

  Is there a way on the security appliance SA520 to remove someone from the DHCP lease client manually rather than setting the DHCP lease time to expire in less time like 4 hours or 2 hours. I was able to do this on other routers by highlighting the connected device and click remove. If not any recommendations on how to handle the device that are attached via DHCP and the person is no longer here, but the lease time is not up. I have set DHCP lease time to 4 hours.                ... View more

Have Cisco SA520-K9, the router is configured for our Internet with a 72.xxx.xxx.xxx number. Cable modem has second IP address that is linked to MAC address of Management software computer. Problem: The second IP address which is a 216.xxx.xxx.xxx number is not finding my Management software computer. If I connect this computer direct to the cable modem, it connects no problem. I need this computer to connect with this 216.xxx.xxx.xxx number so a remote SIP server will do the authentication needed for the Management software. The SIP server is set to look for the 216.xxx.xxx.xxx number. Any suggestions on configuring the router or what is needed for this to work proper. I tried to use the optional port and setup with the 216.xxx.xxx.xxx ip address, subnet, and gateway. Also set to use the MAC address of the Management software computer, but still no luck. Thanks for any help ... View more

Need advise on how this would be the best way to handle. Situation: Have two IP address assigned to our cable modem from our ISP.                The first number is used for our Domain and external internet connection.                The second number we were just assigned to use because we need to connect up to a remote SIP server. Our ISP said that the IP address is assigned to the MAC address of our computer and that all we have to do is allow to connect via DHCP.              DO I setup this computer in the optional WAN port as DHCP? This computer is not joined to the Domain and can not be joined to the Domain because the place with the SIP server do not want to see our Domain. However, this computer is running management software that is connecting to domain public computers and controlling amount of time and printing. The SIP server is setup to see the IP address that was assigned to this computer, but right now all they are seeing is the first IP address. Have not setup the Optional WAN port yet. OH and the two Static external IP's are completely different. Not even same subnet, or anything. ... View more

Switching from RV082 router to SA520 K9 router. In the RV082 router under the setup tab, and then forwarding. I have a udp and tcp service running on port 7195, to our server address 192.168.xx.x. I can not find where I would be able to do the same thing on the SA 520 K9. This is so when people go to our webpage and click on a link it brings up a webpage that connects to our database. The only thing I found was where can setup a service, but it does not point to our server address, which makes it where it does not work. Thank you for any help that gets our web access for our patrons running again. ... View more
