all of my ports on my router are open in my router without me setting it












0














Something very strange happened 4 days ago....



I have been remotely connecting to my workstation using ssh. I use public authentication and my router has been set up to port forward all connections on external/public port 4444 to port 22.



I'm using the dynamic dns service noip.



Something very strange happened 4 days ago. my ssh from my remote laptop started timing out. after further analysis I realized that the noip domain public ip address was wrong, and somehow the noip software stopped working. After fixing that up, I still cannot connect to my workstation through ssh... the error is 'connection timed out'.



I can ping my domain name remotely(outside network) with no problems, and I can connect to my ssh server if my remote computer is in the same network as my ssh server. Yet it times out outside of the network.



Also while I have only port fowarded port 4444, when I check what ports are open on my router using an online port forwarding tool (or unix nmap command outside of the network), I notice that almost ALL of my ports are open! I definitely did not open these ports through my router settings... heck even port 443 is open... a port which my ISP does not allow me to open...



Wtf could be going on? has my DNS been hacked? I checked my server ssh logs (in /var/log/auth.log) and there is no mention of my remote computer (outside network) even trying to logon to my openssh server.



Even though (via nmap and online port checking tools) my ports are open, ssh still cannot connect via port 4444 or port 22 remotely, outside of the network)



What should I do? I'm totally baffled

  • Apparently the port scan is inaccurate. You said the dynamic DNS service acted up - it looks like that is where to look for issues then. Have you tried connecting from a different computer? Tried flushing your DNS cache? Tried connecting using the IP address directly?

Did you check that the IP address provided through the DNS service matches the external ip-address of your router?



If they match your router is acting up or is hacked. Reset the router to factory default, (re-)flash the latest router firmware (to make sure you have the latest security patches) and reconfigure it.

Keep an eye on it. If it starts acting up again it is time to buy another router (from another brand), because you can't trust (it's unreliable or easily hacked) this one.



If the DNS and IP don't match the dynamic DNS service is acting up. Re-register your router with the dynamic DNS service and all should be well. (Give the DNS systems a couple of hours to settle though. Not every DNS service synchronizes quickly so it may take a while for the latest DNS changes to propagate everywhere.)

@Tonny You wrote "3 possibilities: 1 router is seriously misconfigured. 2 router is hacked. 3 router has very sloppy firmware." <--- So thatos what you said, but from what the questioner has just said 8h ago, it is none of those 3 possibilities you mention(or any of his computers). He said that even when he turns his router off, ports still show as open.
