Thank you e-telligent for your help availability.
I have no means at the moment to upload what you are asking for, but tomorrow I will certainly upload what you need.

By the way, I have upgraded one of the 2 EFW from 2.2 to 2.4 (by efw-upgrade from a ssh session), with no errors, but I've noticed to have lost my "proxy" and "port forwarding" configurations... Could this have some consequences on the OpenVPN side too?

Thank you again,
Luca

Hi,

VPN is different from port forward and proxy config

I see that the last one have not "openvpn" (but "nobody") on the "setdnat" and "remoteroute" lines: I'll put in it "openvpn" and I'll make you know.

Thank you for your help,
Luca

Hi,


Add this in sudoers:


openvpn  ALL=NOPASSWD: /usr/local/bin/remoteroute.py

and restart your vpn server

hmm Please check out how do i set. because its not working Sad

This is a test network with esxi. GW 192.168.6.1 not exist.


CLIENT(192.168.1.1/24) --- (192.168.1.72/24) EFW1 (192.168.6.72) --- (192.168.6.71) EFW2 ( 192.168.1.71/24) --- Client(192.168.1.153/24)


Default configured Endians 2.4, no extra settings.. only just all allowed outgoing firewall etc.

EFW1:
-Enabled OpenVPN with one user

EFW2:
-Gw2Gw established to EFW1  bridged to GREEN


EFW1(in ssh):
route -n

-able ping 192.168.1.71
-cant ping 192.168.1.153
-can ping 192.168.1.1

-can ping 192.168.1.153


192.168.1.153 cant ping 192.168.1.1
-and if i run  "tcpdump src host 192.168.1.153" when pinging i see this:

20:18:44.587448 arp who-has 192.168.1.1 tell 192.168.1.153

Hi everybody,

I've finally tried the "single VPN connection" suggested to me and in fact... it's WORKING now Smiley and there is NO MORE packets loss.

What to pay attention to (in my opinion):
1. with two VPN connections (from client to server and vice versa) there ARE routing problems (not better identiified);
2. it is necessary to start "VPN firewall" (Firewall - VPN traffic) at both sites (and configuring an "any to any" rule for test purposes, for example);
3. it is necessary to configure a "Source NAT" rule (Firewall - Port Forwarding / NAT - Source NAT) at both sites.
N.B. with NO "VPN firewall" and "Source NAT" configured, there is NO communication between the two end sites (100 % packet loss with "ping")

There is, however, a last problem. Everything is working right but only in one direction (let's say from the EFW acting as "OpenVPN client" to the EFW acting as "OpenVPN server"), but I would need a bidirectional link.
At the moment only the LAN PCs behind the "OpenVPN client" can connect to the LAN PCs behind the "OpenVPN Server".

I've also tried to "ping" the LAN behind the "OpenVPN client" from an SSH session on the "OpenVPN server", but there is NO ROUTE to the remote LAN. I cannot "ping" the remote EFW acting as "OpenVPN client" itself.

How is it possible to obtain a bidirectional tunnel???

Thank you very much,
Luca

What's your SNAT rule?

In my case the client side has a subnet 192.168.0.0, and the server side 192.168.254.0.

On the client side I've got this SNAT rule:
source = 192.168.0.0/24
Destination = 192.168.254.0/24
Service = <ANY>
NAT to = "name of the openvpn gw2gw connection"

Hmmm, from what I know, this is NOT possible.
It seems, from Endian documentation, that the two LAN MUST have different IP addresses...
