I keep on getting *incorrect router subnet* on the phones.
Any advice

FW - 10.0.0.1
Internal *data lan* - 10.0.0.x

IPO is connected on ports 14-24 of a Cisco 3560G POE switch.
This is how the programming looks like on the switch

mls qos
int vlan 2
ip address 10.0.2.2 255.255.255.0
no shut
exit
vlan 2
no shut
exit
int range gig0/14 - 24
switch trunk encap dot1q
switch mode trunk
mls qos trust cos
switch voice vlan 2
exit
int range gig0/1 - 24
power inline auto
exit
ip default-gateway 10.0.0.1
int gig0/13
switch trunk encap dot1q
switch mode trunk
 
Well, the first thing I see is that your switch is in a different subnet than its default gateway. What is the subnet mask of your internal data LAN? Do you intentionally have your switches running on a separate subnet?

You'll probably want to do one of three things to remedy this (if it's not intentional):

1. Change the switch's IP address to one in the 10.0.0.0/24 subnet.
2. Put a router inside the switch's subnet (10.0.2.0/24) to connect it to the 10.0.0.0/24 subnet (and make sure to configure the switch's "ip default-gateway" to this router's IP address).
3. Change the switch (and/or your LAN) to use a /22 (mask 255.255.252.0) subnet number. That would allow all addresses from 10.0.0.0 through 10.0.3.255 to exist on the same subnet.

Is this the kind of info you were looking for?
