Issue DNAT'ing/Port Forwarding across IPSec VPN tunnel

Hi Pablo and welcome to the UTM Community!

You need a Full NAT instead of a DNAT.

Hi Bob,

Thanks for the reply! I have tried a full NAT with the following settings without success:

Rule Type: Full NAT

Matching condition:

For traffic from: Any

Using service: HTTP

Going to: WAN Address (Site B 2.2.2.2)

Action:

Change destination to: 192.168.14.250 (Web Server site A)

And the service to: HTTP

Change the source to: 172.16.24.254 <<< Firewall inside IP for site B, is this correct?

And the service to: HTTP

Automatic firewall rules: Ticked

What am I missing? If I log initial packets, I see the traffic traverse in the Firewall log but the http request from outside just times out.

Any help greatly is appreciated!

Thank you

Please show a picture of the Edit of the NAT rule.

Hi Bob,

Please see the attached image.

Thank you

That looks good, Pablo.  The source should be changed to the IP of "Internal (Address)" - is that what you have?  You don't need to change the service - just leave that blank.  See #5 in Rulz (last updated 2019-04-17).

If this isn't working, please show pics of the Edits of the IPsec Connection and Remote Gateway.

Hi Bob,

I left the services blank per your suggestion and changed the source to the internal LAN IP object (same IP as before, just a different object name). No luck.

The VPN tunnel is up, I can ping bidirectionally from each site:

Thank you

That all looks perfect, Pablo.  Do you see any related blocks in the Firewall log?
