Virtual IP setup

Hello!

 

I am setting up a service that will live behind the Fortigate Firewall and I have the Virtual IP setup. I have inbound and outbound rules setup that should allow traffic, however when I try to ping or anything else to the virtual IP I don't get any response. Because the Public IP will only be used for the service I don't have NAT setup. This firewall also is only connected to one line out to our ISP who also has us a block of IP addresses. Here is the rule:

Incoming Interface: Virtual Wan Link

Outgoing: Internal Service

Source: All

Destination: VIP

Schedule: Always

Service All

NAT disabled.

 

Other rule:

Incoming Interface: Internal Service

Outgoing: Virtual Wan Link

Source: all

Destination: all

Schedule: always

Service: All

NAT Disabled

 

Is there anything I am missing?

Hi @BrettJ.,

 

Please refer to this article to collect debug flow to see if the traffic is being dropped or not: https://community.fortinet.com/t5/FortiGate/Troubleshooting-Tip-First-steps-to-troubleshoot-connecti...

Those are policies for two different sessions: incoming sessions and outgoing sessions. The outgoing sessions are like for when you access a web site on the internet from your server's browser. Not for the returning packets for the VIP access from outside. So for that direction you still need NAT/SNAT enabled.

 

Then your VIP config is questionable if you forwarded all ports/protocols to the server and couldn't get ping responses. Please share us the VIP config.
Then you need to run sniffing and flow debugging to troubleshoot.
