CIDR is just another way of specifying an ip address.  The following two 
IP addresses are identical, the only difference is how it is specified.  
Some devices prefer one way, other devices prefer the other, and some 
will take either:

Address Specified Old Fashion Way:
    Address: 123.123.123.112, Subnet Mask: 255.255.255.240

Same Address Specified the CIDR Way:
    123.123.123.112/28

So, it sounds like you have two network addresses, as 70. address and a 
24. address.  It sounds like you need to route from one to the other.  
Is this correct?
