After portforwarding, the ports I require access to still remain closed.
Please help. I have tried turning off UPnP IGD and that still didn't work. I have already reserved my i.p. so I see no way in which this shouldn't work.
My modem is a Sagemcom F@ST 5355.

Have you set up port forwarding on modem for port 80 and is there a device or app on your network listening on port 80? Port will not show open unless there is a device / app listening on port 80 and there port 80 has been port forwarded to the device in the modem.
I can't see anything wrong. with your port forwarding rules and port forwarding does work on the F@st5355 so the only thing that would stop the ports not being shown as open Is the ports being blocked by the connection or the PC I'd not listening on those ports.
What type of internet connection do you have and which program are you setting up the port forwarding for?
Port forwarding want fix internet lag. It will fix problems with some peer to peer games were other gamers are unable to join your game. Is the program running when you test if the port is open?
They told me to port forward and which is why I gave it a go. The server being accessed (in the US) has been used for a while and this lag only started appearing after change of modems. We changed modems because we were experiencing drop outs which is reasonable as the modem was quite old. I've diagnosed the issue to be loss of packets but Telstra was pushing me in a different direction and I'm honestly clueless. They have told me that the line is perfect but I don't understand why there is packet loss and connection disruption.
Those stats don't look to bad. FEC errors are errors that were able to be corrected by the extra error correction bits in the data. CRC errors occur when the errors can not be corrected and require a re transmission of the data. On a perfect connection would expect zero CRC errors but you always get some. The 267 CRC over 21 hours could explain the packet loss.
Do you here any noise on the phone line. You are more likely to get a the line fixed if there is noise on the line.
No there isn't any noise. There was an outage recently and I honestly thought that was the reason why. The outage was there was around 2 months and it was apparently fixed recently but the conditions are still the same.
We used to get 200ms which was completely fine but now my son's ping goes higher up to values of 400-500 or or sometimes even jumps higher. This wasn't the case before and no changes to the actual server have been made.
After changing ethernet cables and ethernet ports, there was no change. Using another device and running trace routes supplied the same connection issues. Changing back to my old modem resulted in the usual ping that we would get before. My old modem however is extremely old and we have had experienced some unrelated issues with it which is why we have decided to change.
Pinging directly from the modem to the server results in this:
How many times did you try pinging from the modem? I tried pinging the same destination on a F@st5355 gateway and got 0% loss of frames and a ping time of 208 ms. It could be your link was receiving CRC errors when you run the test.
Tried the ping test again today and had the same results as you, 100% Frame loss. Tried pinging using a 4 G mobile connection and had same result, 100% Frame loss which indicates the server has disabled respond to ping. Because server has disabled respond to ping the ping test is meaningless. I can't explain why the ping test worked yesterday with a delay of 208 ms.
That would explain the trace route as well but this also tells me from the last lines of the trace route that the server is completely fine. I still have no clue what is causing the issue.
Do all 3 lights on the modem have to be green? Just curious because there isn't a light on for the phone one.
To narrow down the problem run a test to your central gateway. To find the address of central gateway log into the modem and go to Advanced > Internet > Gateway. If you are still seeing the high packet loss every few minutes then it is the ADSL link that is the problem.
Are you sure that's how you get there?
After going to advanced there's both a gateway setting and an internet setting. When going to the internet settings no gateway there so I'm assuming you mean the gateway settings?
I'm not sure where to go from there.
Is the address of the central gateway also known as the default gateway? If so, I did the test for that address.
The results for this were really bad.
Yes Default Gateway in the Advanced > Gateway Settings is the same as the Gateway in the Advanced > Internet Settings.
Those results definitely indicates a problem with the ADSL link. It could be the modem, the street cabling or the ADSL port in the exchange. Are you using the same ADSL filter you used with old modem? ADSL filters can go faulty. To eliminate ADSL filter do a test with modem DSL port connected directly to phone wall socket.
I can't remove the filter though? I'm using the filter that came with the modem because there is no way you can use the filter from any other modem because you can't disconnect it from the wires it is connected to.
Yes connect the phone Wall socket to the modem's DSL port using a phone cable.

I went onto the outage site before I was going to talk to someone about this issue and the same outage has suddenly reappeared on the site. This was the same outage "caused by construction" previously and they had said it was fixed before which is so odd? It was confirmed on the website that the outage had ended and now it has reappeared again.
So it turns out this same outage has been going on for months now. This really astounds me...
