Hi, 2Talk dont have their own sub forum and as they are owned by Vocus I have put it here, mods move it if you think needed.

 

Anyway, I have a customer that has a business UFB 100/100 connection that is on CG-NAT, I did not set this up, a previous IT supplier did, regardless its doing all they need.

 

The question I have, is that on the firewall I am seeing continual connection requests on the client WAN interface from three or four sources, these come from subnets belonging to Facebook, Google and Amazon, have not seen any from others but they may be there, these are arriving every 1-3secs, this would imply that there are port forwards or other pin hole through the NAT. 

 

I also see a regular icmp from a 2Talk address, this I presume is a maintenance probe, but can someone please shed light on the reqests from outside. I note port 443 as the source port but seemingly random dst port in each connection attempt.

Do 2talk still have that port forwarding page you can do from the portal? It allowed you to forward ports from a true public IP through to the private IP assigned to your connection. From memory, there was a handful set by default for the likes of 80,443,3389 etc.

 

Weird to see new connections coming in like that from those companies though..

Hi Sam, not too sure, I dont have access to the account I believe the original support guy does. As a result to gain remote access I use the console in one of the UniFi APs to open a shell back to my machine and do a remote tunnel from there.

The PPP password should be their account password*. So if you know one of the DDI's or just the account number you should be able to log in ;-)

 

Edit: *most of the time
