Some help with VPN

Blisk

I need some advice with VPN.
I am not too familiar with VPN and it is first time to do on linux, on windows works but on linux not.

So I manage to setup vpn server on centos, I have server certificate and client certificate and config file for both.

Now server is connected with eth1 to my local network which have IP address 192.168.0.0 on that network is also dhcp server.
other nic eth0 is on public IP and directly to internet.

So I need to connect from my home computer to a work network 192.168.0.0 to have full access to winows server, shared folders and printers.

I can connect to my VPN server but when I try to ping network at work 192.168.0.0 it pings only 192.168.0.1 and my IP address is which VPN gives to me 192.168.0.6

Whatever else I ping on 192.168.0.0 I get reply from 192.168.0.1 Destinatoion host unreachable
And internet on my PC doesn't work anymore and have no access to shared foders at work and to server.

I am missing here something.
My client config is below.

client
proto udp
dev tun
ca ca.crt
dh dh2048.pem
cert cpiclient.crt
key cpiclient.key
remote MYSERVERPUBLICIP 1194
cipher BF-CBC

can someone help me? Why can't I ping my local network server 192.168.0.2
also when I make connection with my pc to vpn, I can't use internet anymore... no website can't be opened

I read all posts about routing and pinging local network but still didn't solve this.

I would remove the line

push "redirect-gateway def1"

from the client-config. This is more the line for the server.

Can you post the server-config too? This way we can check ip-ranges etc. I think you are using the same ip-range inside and outside the VPN. And that's not going to work.
Have you enabled ip-forwarding?

no it didn't worked, it is about a week and I tryed almost all what is on internet and just not working.
I can connect to vpn server but can not acces anything at local network behind vpn

Blisk, check out my thread here: https://forums.openvpn.net/topic13341.html

I think we're having the same problem. I have managed to connect to other PCs on the network now but I'm still having trouble getting WINS to work. I've added both

push "dhcp-option WINS 192.168.1.254"
push "dhcp-option DNS 192.168.1.254"

to my server config but doesn't appear to be having any effect on the client.

Cheers,

Olly

thanks I checked that topic, but I don't have a router after VPN server, because it is on public Ip directly.
I think it is problem with routes on my VPN iptables routing it

I have manage to make internet connection to work, before when I connected to vpn internet stops working.
Now I use this topic https://community.openvpn.net/openvpn/wiki/BridgingAndRouting

but still I can't ping local network behind VPN server 192.168.0.0
