Thanks, now its works

I have a questions, How to make bridge mode?

Server:
daemon
keepalive 10 60
ping-timer-rem
persist-tun
persist-key
dev tun
proto udp
cipher BF-CBC
up /etc/rc.filter_configure
down /etc/rc.filter_configure
server 10.10.20.0 255.255.255.0
client-config-dir /var/etc/openvpn_csc
push "route 172.16.0.0 255.255.252.0"
lport 5000
ca /var/etc/openvpn_server0.ca
cert /var/etc/openvpn_server0.cert
key /var/etc/openvpn_server0.key
dh /var/etc/openvpn_server0.dh
comp-lzo
persist-remote-ip
float

Client:
port 5000
dev tun
proto udp
remote ip.adress
ifconfig 10.10.20.2 10.10.20.1
ping-restart 30
persist-tun
persist-key
tls-client
ca ca.crt
cert esa-adamn.crt
key esa-adamn.key
ns-cert-type server
comp-lzo
route 172.16.0.0 255.255.252.0 10.10.20.1

I don't assign new interface (tun0) and on firewall all traffic on LAN/WAN is permited for my network.
Any idea?

Thx
