Hi, I'm (trying) to run OpenVPN server on a Win2008-RC2. On server side, I have a LAN on [b]192.168.1.0/24[/b] The gateway (which is an ADSL/router with a NAT/PAT redirection on port 1194 to my OpenVPN server) is on [b]192.168.1.1[/b] This Win2008 (which hosts the OpenVPN) is [b]192.168.1.14[/b] Right, Now I'd configured the OpenVPN file "server.ovpn" with : [code]server 10.8.0.0 255.255.255.0 push "route 192.168.1.0 255.255.255.0" [/code] (I'm not on bridge mode) Right. Now, On client side (which is win7-32bit) the connection with the OpenVPN server is ok... I set the IpForwarding on the server. But now, My client can only ping the 192.168.1.14 address (I have 4 others machines on the same LAN) ? Why ? (I can ping 10.8.0.x) Please could you help me ? I think it's a probleme with Win2008 routing but where ? Thanks...

Lan issue on Win2880-R2

Hi,

I'm (trying) to run OpenVPN server on a Win2008-RC2.

On server side, I have a LAN on 192.168.1.0/24
The gateway (which is an ADSL/router with a NAT/PAT redirection on port 1194 to my OpenVPN server) is on 192.168.1.1
This Win2008 (which hosts the OpenVPN) is 192.168.1.14

Right,
Now I'd configured the OpenVPN file "server.ovpn" with :

server 10.8.0.0 255.255.255.0
push "route 192.168.1.0 255.255.255.0"

(I'm not on bridge mode)
Right.

Now, On client side (which is win7-32bit) the connection with the OpenVPN server is ok...
I set the IpForwarding on the server.

But now, My client can only ping the 192.168.1.14 address (I have 4 others machines on the same LAN) ?
Why ? (I can ping 10.8.0.x)

Please could you help me ?
I think it's a probleme with Win2008 routing but where ?

Thanks...

is IP forwarding enabled on the server?
Is there a route on the server-side LAN for the VPN IP range pointing back to the VPN server? if you're pinging a host on the server-side LAN then the source IP address will remain 10.8.x.x - the machine you're pinging will send packets back to the local router, which then needs to forward it to the VPN server again.

JanJust, you're right !!! I'm a jerk :oops:

Thanks for your help.

Another last remark, On my win2008-R2 (my OpenVPN server), I must set the RRAS service to get the ping, do you have an idea why ?

Anyway thanks again....

janjust

hmmm I didn't say you were a jerk 😉

as for the RRAS service - could be that this service does some NATting or IPforwarding for you. I'm not that familiar with Win2008 server...

Snake67, please follow this instruction https://forums.openvpn.net/topic9465.html and find a method that suits you.

Why you need RRAS? Are you using dial up servicing? To combine RRAS with OpenVPN read this: https://forums.openvpn.net/topic9538.html.
