Simple DNAT rule created with Server Access Assistant does not work

CarstenDE

Hi all,

I created a DNAT rule with Server Access Assistant under SFOS 18.0.5 but it does not work at all. Here are the screenshots of the rules:

NAT rule:

Firewall rule:

Service definition:

Here is the TCPDUMP. Out interface Port2_ppp for an internal destination IP looks surprising to me...  

Any help would be very appreciated as I am out of ideas.

Best regards

Carsten

    Hi,

    why do you need an incoming rule to your home assist device, does it not connect through an external server that your application talks to?

    Hi,

    HomeAssistant is only an example as it is a webserver and I can simply check with browser if it works.

    Mainly I need port forwarding for a WireGuard VPN I would like to build up. I need to use WireGuard, as Sophos SSL VPN does not work. I can connect but the internal IPs are not reachable from VPN. I double checked all settings again and again according to the official How-Tos, but no success. Then I switched to WireGuard but now a simple port forwarding does not work, even though all the settings are exactly like in the docs.

    Best regards

    Hi,

    thank you for the details. Have you created a firewall rule allowing the traffic from the VPN IP range to your LAN range?

    Yes, I did. It was not used. Something is wrong with my box.

    As you can see in the pcap above the natted packet is send to the WAN interface but not into LAN. I think that is the root cause. But how can I change that?

    That rule would need to be above the one that is directing the traffic to the WAN.
