Edited 5/25/2016: Changed

# your local subnet 
push "route 192.168.2.0 255.255.255.0" # SWAP THE IP NUMBER WITH YOUR RASPBERRY PI IP ADDRESS

to

# your local subnet 
push "route 192.168.2.0 255.255.255.255" # SWAP THE IP NUMBER WITH YOUR RASPBERRY PI IP ADDRESS

should I change this section?
`# Add route to Client routing table for the OpenVPN Server
push "route 10.8.0.1 255.255.255.255"

Add route to Client routing table for the OpenVPN Subnet

push "route 10.8.0.0 255.255.255.0"`

what should I do here?
# Override the Client default gateway by using 0.0.0.0/1 and
# 128.0.0.0/1 rather than 0.0.0.0/0. This has the benefit of
# overriding but not wiping out the original default gateway.
