To get access from the Internet to the OmniPro II Controler you need to create a pin-hole through the router. U-Verse uses a 2-wire firewall and this requires than any IP address for which a pin-hole is created must have its IP address generated by their DHCP Server. Since the OmniPro II address must be an assigned static IP address no pin whole no access
 
I am looking at solutions to this issue and have some ideas but would like to see if any one elese has looked at this issue. I like the static IP address requiremtnon the HAI side because of security and would like to find a Home Network Solution which may need to be an additional router but that also brings additional issues.

Pete -

AT&T U-verse fiber or DSLAM service? We have DSLAM (DSL-type service) @ office. Our ATT/Motorola router has what ATT claims is a dynamic WAN address, however, this WAN address never changes (so far). We've forwarded a few ports w/in router to OPII (port 4369) static IP & AXIS 4 camera server (RTSP ports 554 to 557) static IP. All good!

Again AT&T technician was initially contacted to confirm these ports were open on ISP side. AT&T was less than helpful.
We persisted & asked for Teir 2 tech. 10 phone-call-hours later ports (pin holes) were open. Solution: Keep trying & don't give up seeking legitimate & reasonable answers from AT&T. Note: Certain Firewalls can block ports.

Other options: #1 Ask AT&T for different brand U-verse router. #2 Use DYN.com service to convert dynamic to static WAN. #3 Contact PortForward.com & use their software to open ports & reconfirm required ports are open. To find the public (WAN) address for your AT&T router go to: Whatismyipaddress.com make note of WAN address returned... check back in a week or so to confirm WAN has/has not changed. Use this WAN address w/ HAI Snap-link Mobile. Good luck. eHc

The ATT/U-Verse setup has the hardware supplied by ATT and consists of a 2wire i3812v iNID and a 2wire i38GH. To get to a host on the internal network you need to have the internal host be assigned a DHCP address by the 2wire hardware before you can create a pin hole through the firewall. Since the HAI Controller requires a static IP Address this setup will not allow any connection from the Internet to the HAI Controller.
 
In Our case we have a static WAN address from ATT/U-Verse and were able to purchase a block of 5 additional public IP Addresses. To get the following solution to work we initialy tested it with the initial WAN Address but that did not work so we used one of the purchased Public IP Addresses to solve the problem. The following is how we did it.
 
Purchased an ASUS RT-N66R Router and pluded its WAN Port into one of the 4 2wire i38GH ethernet ports and let the 2wire DHCP server assign a private IP Address to the RT-N66R WAN Port. WE then assigned one of the purchased Public IP Addresses to the RT-N66R WAN Port, lets use as an example 100.100.100.100.
 
We then DMZ+'ed the RT-N66R WAN Port 100.100.100.100, this process directed all incoming internet traffic from address 100.100.100.100 to the ASUS RT-N66R WAN Port.
 
We then created the necessary port forwarding in the ASUS RT-N66R for the HAI Controler.
 
Now it works
