Hi,
I have connected a remote 877 to the central VPN3020 through an IPSEC tunnel over Internet.
The tunnel works fine and the traffic flows between central and remote LANs.
Now I need to apply a NAT (not PAT) to the source IP addresses coming from the remote site, so I configured a dynamic NAT in the VPN3020 in
âConfiguration | Policy Management | Traffic Management | NAT | LAN-to-LAN Rulesâ as:
[192.168.1.0/24 : 10.30.85.0/28] -> 0.0.0.0/0 (Dynamic)
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.
Best regards.
Paolo.
