My new employer has asked me to determine any issues that could be causing performance issues our LAN. The network has two subnets and one of the first things that I noticed is that I cannot ping computers on subnet A from subnet B. I've looked into this and found a few things.
-I CANNOT traceroute to computers on subnet B from subnet A
-I CAN NMAP to computers on subnet B from subnet A
-Computers on subnet A CAN ping other computers on subnet A and computers on subnet B CAN ping other computers on subnet B
-Computers on subnet A CAN ping and access servers on subnet B
I am relatively new to networking and not exactly sure where to start investigating this problem. Any help would be greatly appreciated. Thank you!
