Agreed. 

Dashboard is saying that if you have that IP 12.194.215.153 with a /26 mask (255.255.255.192)...

Then your subnet / host bitmap is this:

0nnnnnnn.ssssssss.ssssssss.sshhhhhh

where the last two "ss" are the subnet bits in your 4th octet, then you have 6 host bits.

So your subnets are 12.194.215.0, 12.194.215.64, 12.194.215.128 and 12.194.215.192.

So 12.194.215.153 (host address) falls within that 3rd subnet of 12.194.215.128/26.

And you would need to specify that subnet ID (12.194.215.128/26) in your static route entry.

Did you try that and it worked ok?
