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: 188.8.131.52/29
Block size: 8 (5 usable)
Usable IP range: 184.108.40.206 to 220.127.116.11
Subnet mask: 255.255.255.248
Preferred DNS server: 18.104.22.168
Alternate DNS server: 22.214.171.124
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.
1. What is the IP address I put into my Domain Name Service? I have entered: 126.96.36.199 (Actually, I have tried all five static IP's, including the public IP of 188.8.131.52, 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?
