Has anyone been able to get port forwarding to work properly on the G3100?
Other posts have been made and "solved" but the solutions are not real solutions.
There appears to be a bug in SW 1.3.6.27, HW 1103.
Thanks!

So I double-checked what I called Method 2 -- setup port forwarding by entering the Firewall Menu and then selecting the Port Forwarding option.
While checking that, I recognized I was making a mistake in the configuration -- I was not leaving the Source Port at the correct setting of ANY. After fixing that mistake, port forwarding worked as expected.
So to help others, if you are setting up a server on your LAN that you want others to access from the internet:
Source Port: Any
Destination Port: Port Number for your service
Forward to Port: Port Number for your service
I will mark this ticket as SOLVED.
Thank you Dear dslr595148 Platinum Contributor III for sticking with this.
#1 You use an inbound client side port checker like http://www.pcwintech.com/simple-port-tester or from https://portforward.com/help/portcheck.htm then be sure that:
you are forwarding the ports that you want to check and the server that you are trying to forward is NOT in the listening state.
Stated reason that the server that you make sure the server trying to forward is NOT in the listening state when using an inbound client side port checker, when using this kind of port checker - it will try to listen on that port and you can not have two servers listening on the same port at the same time.
#2 Or instead of an inbound client port checker:
a) Download and Install a packet sniffer. A packet sniffer like, tcpdump. But please note tcpdump is not the only packet sniffer that exist.
b) For tcpdump. tcpdump -p -n -i eth port 5154 would be a good command to start with). If you see incoming TCP SYN packets (not SYN/ACK), or incoming UDP packets from an IP which did not have an outgoing packet first, then the port is open.
c) and use a client side port checker like https://www.yougetsignal.com/tools/open-ports/
d) Note #1: If the port number is not 5154, then replace that port number with the one that you are testing.
e) Note #2: If the interface is not eth, then replace that interface with the one that you are testing.
f) Note #3: To test more than port...
tcpdump portrange 5153-5155
tcpdump port 5353 or port 8080
...or you can combine it...
tcpdump portrange 5153-5155 or port 5353 or port 8080
#3 Once you know that the port is open from the outside (not talking about from behind the router), see Port forwarding only works seen from outside my local network?
#3 If you need any help getting the port sent through the router, please post.
#4 Likewise if you need any help getting the port to show as open after you use a client side port checker (or a packet sniffer and a web based port checker), please post.
Dear dslr595148 Platinum Contributor III,
I am not sure if you are a human or bot, but I will assume for a minute that you are a well intentioned prolific Verizon forum poster trying to help as many people as possible.
I am familiar with methods for testing if ports are open which appears to be the intent of your post.
Thank you for your help.
Best regards,
#1
a) I do not have FIOS or ever have.
b) I do not have any FIOS routers or ever have.
#2 While I do not have FIOS or any FIOS routers or ever have had FIOS/any FIOS routers, I have used the methods that I listed to tested ports with the router(s) that I have.
#3 No, see answer number 1a and 1b.
Thank you for the honest reply and for trying to help.
Unfortunately tests do nothing but confirm what I already thought was the case -- port forwarding is broken on the G3100.
I called and spoke to LaTanya last week (on 5/21)-- she was unable to confirm or deny the problem. She was also unable to get anyone on the phone who could troubleshoot a higher level tech problem. She was supposed to call me back but she never did.
I plan on calling again tomorrow (Tuesday, 5/26).

I had to delete the entry in Port Forwarding Rules that I had set up for the port I needed and instead, specifically identify the ports in the Firewall - Port Forwarding section. It seems like creating a port forwarding rule for my application and applying it in the firewall doesn't work. In the Firewall section, I simply had to use the "Custom Ports" option instead of the application rule that I had created previously. Now it works!

Does that help you???
I have tried both methods and neither has worked.
Method 1: Define a rule under Advanced/Port Forwarding Rules and then apply it under Firewall/Port Forwarding
Method 2: Make a new rule under Firewall/Port Forwarding
Super confusing naming -- horrible user interface design. With that said, I have tried both methods and neither works.
