Hello Viraj,

using a /24 mask is better for LAN:

you need to use NAT to provide internet access

int fas0/0

ip address 10.10.10.1 255.255.255.0

ip nat inside

int ser0/0

ip address 94.56.x.y 255.255.255.252

ip nat outside

access-list 11 permit 10.10.10.0 0.0.0.255

ip nat inside source list 11 interface ser0/0 overload

ip route 0.0.0.0 0.0.0.0 94.56.x.z

! where 94.56.x.z is the next-hop on the wan interface

Hope to help

Giuseppe
