Issue sending traffic over openvpn

@kr0490 said in Issue sending traffic over openvpn:
So just to be clear the tunnel network which is the 10.X.X.X is supposed to be different from the remote network which i have as a 192.168.3.1/24 network
Yes, but both are NETWORKS.
And a /24 network EVER has a 0 at the end! -
@kr0490 yep i checked, not sure what else is causing traffic to not route accross :(
-
@kr0490
Consider that the destination device can block access from the remote or from outside in general by its own firewall.For further investigation post the routing tables of both nodes.
-
@viragomann I have an allow all rule on the open vpn interface on both sides

I don’t see routes for either remote networks on the other side boxes -
@kr0490
Cannot find any matching VPN tunnel here.
On the server you have 172.16.12.0/24.
And on the client 10.0.0.2. -
@viragomann that 172.16 is my personal vpn from my laptop to the server, not the site to site, i checked the site to side is both set to 10.0.0.1/30 on both sides
-
@kr0490 said in Issue sending traffic over openvpn:
i checked the site to side is both set to 10.0.0.1/30 on both sides
But it is not shown up on the server. So there might be something wrong in the settings.
-
@viragomann hmmm I’m not sure where it would be
-
@kr0490 I checked and can’t find a misconfiguration with ips. Do I need to create some kind of routing entry?
-
@kr0490 by adding an interface i now see the proper route tables showing, below is an example from the server. But still cannot ping or access things on the opposite network.

@kr0490 got it working, added interface on both for open vpn, and then added some firewall rules, now it’s all good! Thanks for all the help!
