How do I find out which ports are open on my network?

I am trying to use port forwarding to view security cameras over the internet. My camera system, using DHCP, has an IP address of 192.168.0.100. The data is set to come out of port 1026. The camera system is plugged into a hub with an IP address of 192.168.0.1 (set statically). That hub is, in turn, plugged into a DSL modem (which can also work as a Wireless Hub/DHCP server) with the internal address of 192.168.0.2 and an external address of 71.38.68.47. Internally, I can see all devices on the network whether I am plugged into the hub or have linked to the wireless modem. I have set port forwarding on the DSL modem to forward 192.168.0.100 port 1026 for both TCP and UDP protocols. It seems like I have done everything right. I have set-up a similar arrangement in the past with success. But currently, I cannot call the WAN IP address of the modem : port number of the cameras and get the picture. Maybe it is in how the modem and wired hup are linked. Appreciate any help.
