Hey experts. I am working through an issue that is affecting my Sophos updates and Websense filtering. Each service is on a different server but located on the same network. We recently put a Cisco 3750x into production which replaced a Nortel 325-24G. All of our network traffic comes to this switch before going out to a Contivity 1730 which is managed by a state agency. I've worn out the state support and they show that the firewall at our location should be able to allow ports 8192 and 8194. I haven't done much with the 3750x so I'm not sure if that switch is in play with the inability of the Sophos server to get updates or the Websense filtering to function properly. Both of the issues relating to Sophos and Websense occurred when we put the new Cisco switch in place.
How do I test whether the Cisco switch is or isn't blocking traffic on those ports (if that is even possible)?
Thank you in advance for your help and time.
