Hi Ajayi,
It looks like the problem comes from your subnetting . First of all you have to know that with your /25 you can have two /28 one / 27 and one /26 . Let’s subnet this network like this:
The two /28 can be:
64.110.88.0 255.255.255.240
64.110.88.16 255.255.255.240
The /27 can be : 64.110.88.32 255.255.255.224
And the /26 which is directly connected to your Ethernet : 64.110.88.64 255.255.255.192
So your routes should be:
Ip route 64.110.88.0 255.255.255.240 64.110.88.68
64.110.88.32 255.255.255.224 64.110.88.68
64.110.88.16 255.255.255.240 64.110.88.68
Try these settings and tell us if it is ok. Please advise if your router is a linux box or a cisco router. This can help.
Regards,
Aboubacar.
