I've had a route in Windows Server 2008 R2 RRAS that's been working for a long time, which is 192.168.100.0/24.
The network on the other side of that link recently added a new subnet, 192.168.101.0/24
So, naturally I thought to myself, I would just modify the existing route to the following:
But no go. Nothing on the new subnet goes anywhere.
But, if I make the following setup:
Which is effectively the same route as above, just more verbose, works perfectly.
I don't mind having the two routes, but I'd really like to know why it's nessesary. Any ideas?
