[SOLVED] Problem with Net2Net. Client ping to server, but server don't ping...

Hi all,
I'm trying to use the OpenVpn as a Net2Net. My networks like this:
PC1 ------| |PC1
PC2 ------| |PC2
PC3 ------| "Site 1" INTERNET "Site 2" |PC3
|-------- LAN------ EFW ---- OPENVPNSERVER .... *_____VPN-Tunnel_____*..... OPENVPN GW2GW ---- EFW --- LAN--- |
SITE 1(EFW 2.2)
IP: 192.168.254.2/24
ROUTE
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
189.115.224.1.d * 255.255.255.255 UH 0 0 0 ppp0
1.1.1.0 * 255.255.255.0 U 0 0 0 eth1
192.168.254.0 * 255.255.255.0 U 0 0 0 br0
default 189.115.224.1.d 0.0.0.0 UG 0 0 0 ppp0
SITE 2 (EFW 2.3)
IP: 192.168.0.15/24
ROUTE
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
200.217.72.224 * 255.255.255.255 UH 0 0 0 ppp0
192.168.0.0 * 255.255.255.0 U 0 0 0 br0
1.1.1.0 * 255.255.255.0 U 0 0 0 eth1
192.168.254.0 * 255.255.255.0 U 0 0 0 tap1
default 200.217.72.224 0.0.0.0 UG 0 0 0 ppp0
From the Site 2, I can access all the PC'S at Site 1. But from the Site 1
(Server) I can't access PC's at Site 2.
But I can ping (from all the PC'S in SITE 1) to EFW (CLIENT) if I ping to the IP it
picked up from the VPN connection. How could I solve this issue?
Thank's all.

Hello all,
I solved my problem!
I only needed to add the network of SITE 2, in the:
VPN -> OPENVPN SERVER -> ACCOUNTS -> USER ACCOUNT -> NETWORKS BEHIND CLIENT ->
192.168.0.0/24
Now, all the PC'S and servers can ping to each othe

Forgive me if I post my problem in this thread, but my configuration is very similar to this one, with the exceptionthat I'm using OpenVPN with digital certificates (option "X.509" in OpenVPN Server - Advanced).
I'm using Endian CE 2.4.
The VPN connection comes up without problems and is very stable, and from each site I can ping the EFW of the other side (I can ping its Green Interface IP): I can ping it from the LAN PC, and not only from the EFW of the remote site. Forgot to mention that I've already created 2 tunnels, in both directions.
But when a PC in a site (for example site 1) try to ping a PC on the other site (site 2), the first packets obtain a "reply to" and everything goes well, but the following ones obtain a "destination unreachable" from the local EFW...
The thing even more unbelievable is that if a run a "continuous ping" (ping -t), from time to time I obtain again a "reply to" from the remote site.
It seems like Endian VPN tunnel drops the packets: it drops a 70% of the traffic...
One of the two EFW is running on a VMware ESXi virtual machine, but I do not think that this is the origin of the strange behaviour...
Did someone else experience this behaviour and find a solution?
Thank you very much,
Luca
