Trouble with port fowarding

[egh]

Hi,

I am having some difficulty with port forwarding with my Pace 4111N. Each time I try to connect, it fails. Then, generally, the next time, or time after, it succeeds. Here is an example:

Code: Select all

  ❤ telnet XXX.XXX.XXX.XXX XX
  Trying XXX.XXX.XXX.XXX...
  telnet: Unable to connect to remote host: Connection refused
  ❤ telnet XXX.XXX.XXX.XXX XXX
  Trying XXX.XXX.XXX.XXX...
  telnet: Unable to connect to remote host: Connection refused
  ❤ telnet XXX.XXX.XXX.XXX XXX
  Trying XXX.XXX.XXX.XXX...
  Connected to XXX.XXX.XXX.XXX.
  Escape character is '^]'.

This only seems to have started in the last day or so. Before that, all was well.

Thanks for any help!

egh,
I can't reproduce the trouble you're experiencing. I tested out the pinholes you have set up on your 4111N and was able to establish a telnet connection consistently using each of them.

Is the problem still occurring? Does the problem occur when you are telneting from a device from within your LAN or from outside of your network?

Hi Chris,

Thank you! It seems to happen from inside and from outside. Here is from outside:

Code: Select all

egh@tsunami:~$ telnet XXX.XXX.XXX.XXX XX
Trying XXX.XXX.XXX.XXX...
telnet: Unable to connect to remote host: Connection timed out
egh@tsunami:~$ telnet XXX.XXX.XXX.XXX XX
Trying XXX.XXX.XXX.XXX XX...
Connected to XXX.XXX.XXX.XXX XX.
Escape character is '^]'.

I will keep looking into it. Connecting to the server using the local IP (192.168.1.x) works fine.

OK, I was getting a lot of breakin attempts over ssh. Blocking the offending IP seems to correct the issue.
