So I've got a network with multiple vlans and I've got a bit of an issue with it. One of the networks is 10.165.24.0/21 which would be 10.165.24-31.254 if I did my math correct. The router is setup with a path to that network and anything on 10.165.24.x will ping fine, but when I try to pign 10.165.25.x it gets no response. Even stranger, the 10.165.25.x range is able to ping anything on the network... What did I mess up?
