Would like to enable Telnet for R6200

I tried Port Forwarding, and Port Forwarding Telnet. 

 

I tried some of the tools designed for Windows and a C program and a python script and a TelnetEnable1 and a TelnetEnable2 for Windows tools.

 

I tried the local host, local host and the specific host reserved via port forwarding for Telnet. I tried the password they recommended and the password of my router.

 

I am still unable to get Telnet to work from my computer, any suggestions?

   Why?

 

> [...] for R6200

 

   Firmware version?

   If you want to Telnet _into_ the R6200, then port forwarding won't
help.

   "tried" is not a useful problem description.  It does not say what
you did.  It does not say what happened when you did it.  As usual,
showing actual actions (commands) with their actual results (error
messages, LED indicators, ...) can be more helpful than vague
descriptions or interpretations.

   I don't know what any of that means.

 

   Telnet access to Netgear routers is not a supported feature, and it
seems to have disappeared from recent firmware versions on models where
it had worked previously.

 

   Possibly interesting:

Re: Would like to enable Telnet for R6200

yes, sorry, I wanted to use Telnet to check SMTP connections but also to get a feel for the RFC requirements. I enjoy for example learning whether an email would be RFC 5322 compliant or not. It's of interest to me since I am running some mail servers and I want to understand the handshaking signals. It's also of interest to check the ports.

 

Long and short, thanks to a Microsoft representative, I realize that the ports such as port 25 are blocked by my ISP. So I can still check through a proxy network or use other ports that are not blocked such as 587.

 

The information you interpreted such as telnetting into the router is perhaps of interest but it's not actually pertinent to me at the moment.

 

Thank you for your help.

   "connections" between what and what?  Without a better idea of what
you're actually doing, it's tough to say what should or shouldn't work
and why.

   You can talk to a server on your LAN from a client on your LAN
without any port forwarding on your router.  Or any interference from
your ISP.

 

> [...] I realize that the ports such as port 25 are blocked by my ISP.
> [...]

 

   That would be typical for residential service, but I'd expect it to
affect only incoming connections.  Ask your ISP?

 

   For the usual problems with port forwarding, see:

Re: Would like to enable Telnet for R6200

they block some incoming connections such as port 80 but they also block incoming and outgoing for port 25 and some others like file sharing.

 

As far as what I had in mind to do was to test my SMTP servers. I have several VPS, one of them is a bundled package that is mostly exclusive to email while the other was more for websites so I need for example, send a bill to a client if they check out by email or if they submit a forgotten password request. So I was just learning how to do things like that and setting it up. 

 

Here's the information on what specifically I was looking to do:

Use Telnet to test SMTP communication on Exchange servers | Microsoft Docs

 

because port 25 outgoing is blocked I will simply test it from the VPS, if needed.

 

There was thankfully no problem with Netgear.
