Hello Ahmed and welcome to the forum.
Please can I ask you not to bump threads which have been dead for 6 years, especially when there is a very good pointer to the answer in that thread a couple of posts earlier (/etc/openvpn/clients.conf).

Hello guys,

I need to edit the server config file so that I can change the port number which OpenVPN listens on, does any one know where I can find the file ?
I have ClearOS 7

Thank you.

OK - that is the correct syntax. We're looking good, I can connect and now get to my two main subnets (192.168.10.0/24 and 192.168.13.0/24).

Not 100% sure what the issue really was, I ended up ditching the whole system and starting from scratch (previously my boss was doing the install of the ClearOs, then I was taking over the config, this time I created the VM and install myself)

I am still having some issues with another couple of subnets, but I think this is outside of the scope of this thread. Those subnets are part of another site, that is routed over a site-to-site VPN (done by firewalls). That's going away and we are moving to a true point-to-point circuit. I'm waiting until then to deal with the routing.

Thanks for all the assistance

PS - I had added the .10.0 network originally because I could not access it, and did not get the route for it (the route was not being pushed by the config). So something must have been borked from the get-go

When you do the EXTRALANS bit and restart OpenVPN, have a look in /etc/openvpn/clients.conf. You should see a "push-route" line for your normal LAN and for any other LAN defined by the EXTRALANS parameter. I am not sure why you are adding a line for 192.168.10.0/24 as you say that is the ClearOS LAN subnet. Have I missed somethng in your network topology?

[edit]
Which O/S is your client running on and, if necessary, are you running as administrator?

Also, a tracert to a server shows the next hop to my gateway.

I also attempted to add a static route on my PC, but seem to get the same issue.

Hm, I must still be doing something wrong. Running as Admin and added my 192.168.10.0/24 to the EXTRALANS

 

[root@ClearOS ~]# cat /etc/sysconfig/network

NETWORKING=yes

HOSTNAME="ClearOS.MyDomain.com"

NOZEROCONF="yes"

EXTRALANS="192.168.10.0/24"

Good enough - I'll test and find out the proper syntax

Cheers

I have only one extra LAN specified:

EXTRALANS="192.168.10.0/24"

Judging by the openvpn init script, separate the LAN's with spaces and only one pait of double-quotes, so:

EXTRALANS="192.168.13.0/24 192.168.200.0/24"

Commas may also work but I am not 100% sure of my scripting.

Restart Openvpn after making the change.

Actually, what's the syntax for the EXTRALANS? I don't have this line in there, and I'll add it. M yassumption it's soemthing like:

EXTRALANS="192.168.13.0/24","192.168.200.0/24,"."..."
-or-
EXTRALANS="192.168.13.0 255.255.255.0",.....

I guess my questions are
How is subnet defined
I assume I use quotes
Do I coma separate the subnets or new lines for each subnet.

Awesome, I'll give it a try and report back

If you're using Vista or Win7 you need to run the Openvpn client as administrator or routing will not work. If you want to push extra routes to the client, specify the subnets in the EXTRALANS line of /etc/sysconfig/network. Then the routes will be pushed automatically when the client logs in.

As far as I can tell I am using a client-server tunnel - it's an out-of-the-box setup, and the OpenVPN is the only thing I am using it for. Using the windows client.

I connect just fine, and get an IP (10.8.0.x), but cannot ping/communicate with the remote network (192.168.10.0). I will need to setup more routes, as my remote network has multiple subnets that I'll need access to, but the .10.x is the first step (ClearOs server is in that subnet).

Note that the local PC's subnet is not in conflict with either subnet.

Which routing are you trying to set up. If you are using a client-server tunnel then you should not need to do anything very much. It should work out of the box.
