Now when I enable the LAN-to-LAN NAT, the traffic stops to flow.
I have checked on the VPN3020 and I saw the NAT applied (in âMonitoring | Statistics | NATâ). I have sniffed the traffic on both LANs and the diagnosis is that the traffic stops into the VPN3020, perhaps because it is filtered away.
The question is: what I have to check or what I have to change in order to have the NATted traffic acceptable to the VPN3020?
Note that I have not modified the filters already configured and that I do not see any route for the 10.30.85.0/28 in the VPN3020 routing table.
Activating IPSec transparent mode on the VPN Concentrator creates non-visible filter rules and applies them to the public filter. The configured port number is then passed to the VPN Client transparently when the VPN Client connects.
