Is it possible to configure DHCP option 150 on the RV220? I have a Cisco 7940 IP phone that is trying to connect back to my office. The VPN is up and I can ping the relevant server but I can't see any way to configure the DHCP option.
What is the Advanced DHCP page configuration supposed to do? It would seem that the CIsco phone should work with option 66 but when I configure the advanced options and enter my TFTP server it does not appear to get used.
Yes! There is a packet capture feature on the RV220W which will allow you to capture this.
Administration > Diagnostics > Capture Packets
These packet captures can be opened and viewed in Wireshark or any other tool that can view .pcap. With this data you should see the DHCP request and response containing the DHCP option with the server IP.
If you have any trouble with this, please feel free to contact us at the SBSC. Here is a link for contact!
