Hi,
I am helping out a friend of mine that has Comcast business class internet with a static ip address. I setup the comcast modem/router which is a Netgear CG3000DCR gateway to allow a passthrough mode whereby the DHCP and firewall are disabled. The gateway is connected to a Linksys E2500 router which handles all of routing. I am having trouble accessing the networked DVR outside the network, over the internet. The DVR along with all other computers are connected to the Linksys router. I setup a free DDNS service so that we could access the DVR by using a domain and opened the correct ports in the Linkysis router to view the live stream but I still can't connect to it. I called comacst and the CSR told me he couldn't ping the Static WAN IP that was assigned to the Linkysis router. He said it's probably a setting in the router that's preventing the IP from being seen from the internet. I checked all the settings on the Linksys router and couldn't find anything that appeared to be blocking the access to the DVR. I even used DMZ to the IP that was assigned to the DVR and it still didn't work. We have a similar setup to the picture shown below. I can access the DVR from the local network but as soon as I try from the internet it doesn't work. Does anyone have any suggestions on what's causing the issue were facing? Thanks for your time.
