I have a site I'm investigating and I've found they have multiple connected Cisco devices. I initially thought I was unable to telnet into their router at all, but upon further investigation, if I telnet into a connected switch, I can then successfully telnet into this router.
Site1 --(telnet)--> router 172.16.232.2 (doesn't work)
Site1 --(telnet)--> switch1 172.16.232.5 --(telnet)--> router 172.16.232.2 (does work)
I can ping the everything successfully throughout but I cannot telnet or gather SNMP data, which is my ultimate goal so I can set it up for SolarWinds NCM.
