I have a home network with a 3G Modem that provides internet. I just put in some security cameras and I'd like to access them remotely. The camera system comes with a free DDNS service and I've got is all set up (at the provider, in my camera system, and port forwarding set up in my router). But, when I tried to access it using the DDNS address, I started to realize that my ISP is blocking traffic from outside to inside. I went to http://mypublicip.com and got the IP. I tried pinging the IP and got no replies:
PING 220.127.116.11 (18.104.22.168): 56 data bytes Request timeout for icmp_seq 0 Request timeout for icmp_seq 1 Request timeout for icmp_seq 2
HOWEVER, I also have some WeMo devices in the house that I can control remotely. I think the WeMo devices are somehow calling out to a remote server to maintain a connection in order to receive commands.
So, my question has two parts:
- Is there a way to make my port forwarding and DDNS solution work with my security system even though my ISP wants to make it hard for me to do?
- If not, is there a way to do what I want to do that might be somewhat similar to how the WeMo devices work remotely?
