Telnet connection from home network

Hi

I'm trying to setup my first home lab but I'm having an issue with telnet from my home network. I have successful connected an router 2811, switch 3560v2 and an pc1. 2811 gets internet access form my home router (netgear) and switch and pc1 gets access through 2811. I can ping 2811 from pc1(192.168.2.2) and have access through telnet. When I try to telnet from pc2(192.168.1.2) to 2811 it doesn't work, however I can ping 2811 and I get answer but no telnet connection. Thank you in advance!

Here is config print:

Hi

 

Almost done :). Everything works fine with windows firewall disabled. When enabled telnet doesn't work. I have tried to add custom rule to windows firewall but it doesn't work.

 

 netsh advfirewall firewall add rule name="Allow Inbound Telnet" dir=in program= %SystemRoot%\System32\tlntsvr.exe remoteip=localsubnet action=allow

 

netsh advfirewall firewall add rule name="Allow Outbound Telnet" dir=out program=%SystemRoot%\System32\telnet.exe protocol=tcp localport=23 action=allow

 

So once you are telnet to 192.168.1.88, you can't telnet to the other routers? Or you are trying to Telnet Directly to the other routers from your Home PC?
