ACL to protect telnet or ssh on GS110TPP

Hi all,

 

I have a GS110TPP on firmware 7.0.9.12.

From reading and experimentation I have figured out that the unit has both a telnet server (port: 60000) and ssh server (port: 22); each of which can be enabled via the web UI:

 

Maintenance > Troubleshooting > Remote Diagnostics

 

My question is whether an ACL can be constructed to permit connections to telnet on this switch only from a single IPv4 address (or range). I've tried a bunch of permutations but it never seems to work and Netgear Support were particularly unhelpful by only sending me generic ACL articles.

 

Ideally, I'd like to have an ACL for ssh too but I know it's not exactly supported.

On that note, I see that ssh is supported for the "GS110TP". Is there any way to get a firmware working for the GS110TPP?

 

Thanks,

Luis

    All GS108Tv3 / GS110TPv3 / GS110TPP share the same firmware version, v7.0.9.12 as of writing.

     

    Talking of the Netgear Lite Command-line Interface (CLI)? Initially, the Lite CLI was introduced for select models only, in this line the GS108Tv3/GS110TPv3 7.0.9.5 and above, indeed. Well possible, this development is stuck ...

      Thanks very much for the reply. I figured as much.

      As per the OP, is it possible to configure an ACL of some sort to protect the telnet port on the switch?

      I'm able to automate the enabling/disabling of PoE on each port via telnet but really don't want to leave that unsecured.
