openvpn client and browsing the internet via openvpn server

[ikedw]

Hello I need help
I configured a server with openvpn and linksys WRT54 ddwrt.
It all works but using the router kraun KRRS the vpn client surfs the internet while using the router dlink 2750U does not go on the internet.
I would like to know if I can change any parameter.
I already created the static route to the openvpn server and enabled the redirect.
-gateway.

my configuration server
server 20.8.0.0 255.255.255.0
dev tun0
proto tcp
port 443
keepalive 10 120
push "route 192.168.0.0 255.255.255.0"
push "redirect-gateway"
dh /tmp/openvpn/dh.pem
ca /tmp/openvpn/ca.crt
cert /tmp/openvpn/cert.pem
