It looks like you have are using a block of private class B's as a
contiguous CIDR range including 172.16.x.x and 172.17.x.x
I played around with the IP's using various on line subnet calculators
http://jodies.de/ipcalc?host=172.16.30.4&mask1=15&mask2
Address: 172.16.30.4
Netmask: 255.254.0.0 = 15
Network: 172.16.0.0/15
Broadcast: 172.17.255.255
HostMin: 172.16.0.1
HostMax: 172.17.255.254
It looks to me like the broadcast address is wrong.
Or are you trying to treat 172.16.x.x and 172.17.x.x as separate class B
subnets?
