Firewall Pinholes and Port Forwarding

just recently had business class U-Verse 50/10 installed.

I have NOT been able to configure my AT&T Pace 5268AC modem/router to allow port forwarding in the following manner:

 

Inside the LAN: Need the following IP address to receive traffic on these ports:

Static IP: 192.168.1.60, ports 5000-5001 (NAS server)

Static IP: 192.168.1.54, port 80 (http)

Static IP: 192.168.1.55, port 5900 (VNC)

Static IP: 192.168.1.56, port 21 (FTP)

 

I have a block of 5 static IP's as describe by AT&T installation tech: 

CIDR block: 75.17.97.16/29

Block size: 8 (5 usable)

Usable IP range: 75.17.97.17 to 75.17.97.21

Subnet mask: 255.255.255.248

Preferred DNS server: 68.94.156.1

Alternate DNS server: 68.94.157.1

 

NO help from AT&T tech support can configure this network to allow this unsolicited traffic to pass to these internal, behind the firewall servers.

I have been on the telephone with AT&T tech support for two days, one day for 4 hours. NO person is able to explain, or fix this with remote access to my PC.

I have Googled this, and followed the tips found in the search. -- NO HELP!

Additionally, I signed up for PAID tech support for $15/month. NO person in this support group can either remotely control my PC, and make this work, or give me advice towards a solution. I find this incredible that this should be so hard, as this is a common request by many business class customers who are running servers behind the firewall in their local business.

 

QUESTIONS:

1. What is the IP address I put into my Domain Name Service? I have entered: 75.17.97.18 (Actually, I have tried all five static IP's, including the public IP of 71.130.58.51, all with NO help)?

2. Why is this so difficult for a common solution that any off-the-shelf router/firewall can perform with a few minutes. Surely, AT&T has seen this issue and hopefully has an answer?

3. What do I need to do to get this common function to work within the AT&T U-Verse network?
