Alright, so I can understand that. Next up, I have some Cisco IP Phones which need DHCP option 150 specified. I've been doing this with the dnsmasq built into Tomato. How can I fix that if I rely on the U-Verse gateway?
If you don't have too many Cisco phones, just use the Alternate TFTP option in the network configuration on the phone and manually specify the TFTP address. This is what I do to any Cisco phone that I send home with someone, as that's all option 150 does...just using DHCP.
