You have two different types of IP addresses on your system. You have an
external address or WAN which is 74.239 ... Your router sets up a group of
internal IP addresses, LAN, which makes connection to your computers and
devices possible. On your main computer, go to run, type in "cmd". When
the command prompt window opens, type in "ipconfig /all" (no quotes). You
will get a list of the network info for that machine. The IP address will
be something that starts with 192.168.xxx. xxx. You will also see the
address of your router or default gateway and your subnet mask. The first 3
sets of digits 192.168.xxx have to agree on all your devices. If you are
having the IP address automatically assigned, this isn't a problem. But in
your case it sounds like your security device has a fixed IP address,
192.168.1.102. The 1 or 001 in the 3rd set of digits is the problem. If
you network is running on 192.168.0.xxx then a device with an assigned IP
address of 192.168.1.xxx won't work. You need to either change the fixed IP
address of your device or change the IP address range on your router. You
should be able to do either although I think going into the settings on your
security device will be easier.
I think your old router already had an internal address scheme that matched
your security device. I've had routers come with 192.168.1.xxx ip addresses
configured by default. Your router, too, should have a place under the LAN
settings where you can set the range of IP address it uses. It will be
under LAN or DHCP settings. That will usually look something like
192.168.0.2 - 192.168.0.256. You can reset that to 192.168.1.2 -
192.168.1.256. I'm starting the range with a 2 because usually your router
is assigned the 192.168.1.1 address.
Hope this makes more sense.

Thanks for the help Ben and I'm not sure I understand.
My DSL modem has a fixed IP of 74.239.177.61
The security system has it the setup
HTTP 8080
Server 6036
IP 192.168.001.102 (leading zeros as that is the way it is displayed)
When I was using the Linksys the port 8080 was forwarded using that IP
but this 7550 won't let me do that. It comes up and says something about
using that address in a subnet.
I can't find anything that says subnet to input to.
I'm not at the shop now so can't talk to the actual items but will maybe
later today and will have better info.
