LoopBack NAT is not working upon accessing WEB Application Public IP in Local Network

Hello,

Could you share the NAT rule/ loopback rule and the Firewall rule you configured to match the NAT rule? 

Could you also share any logged traffic from Source->Dest on the Log Viewer and packet capture if the FW rule matches the NAT rule? Kindly confirm as well that DNAT rule is not above the loopback nat rule as it may match the DNAT as well.

Thanks

Here is the Firewall Rule,, NAT Rule and Loopback Rule.

here the logs when accessing SErver using public IP via local network

Here is the packet capture

Thank you Raphael

Here is the Error whenever i tried to access the Web Server via local network using public IP access

It was accessible when i'm trying to access it externally!

Hello, 

Thanks for taking the time to share details.

Could you create a FW rule to match the Loopback NAT rule

So the FW rule would look like this:

Source Zone: LAN

Source Networks and devices: *LAN Network*

Destination Zone: DMZ/LAN

Dest Network: *Server Public IP

Services: *Specified services

Then confirm that Loopback NAT rule is above the DNAT NAT rule. 

Regards,

Hi Rap,

We already have that policy for our further troubleshooting but still no to avail.

we tested also to put the loopback NAT rule at top of DNAT Rule, issue persist.

thank you and regards,
