I have a Cisco SG350-28 switch I have configured, It's the 2nd switch in line of my route switch. I used to have connectivity to it until a 3rd party installed a new piece of equipment on my VLAN.
I can ping the switch (10.2.3.3) through my firewall and through the route switch at the remote location. I have access to the route switch(10.2.3.2) via SSL, telnet, and SSH. However when I attempt to access the 10.2.3.3 switch, it get a connection time out via telnet and SSH. I also get no site available via SSL. However, if I go on site, I can access all services from within the physical realm of the VLAN just not remotely.
My firewall rules dictate I have access to the entire 10.2.3.x subnet and it's held true aside for this single switch.
Originally I thought it was an IP confliction with the new devices, but all of my clients have internet connections and can access everything they need that are on this switch within the same VLAN. I'm not quite understanding what could cause this. Any ideas? I'm just lost on how it worked until just recently, now I have no access to this switch unless I go to the physical location and either use a computer on site or serial into the switch.
