Forwarding ports with intermediate router

Enrique_C

Hello, our scenario is:

Internet —— Router (192.168.0.1) —— (192.168.0.2) Zywall USG20 (192.168.9.1) ———- PC (192.168.9.100)

In our router we have create a forwarding rule - all external traffic by 1433 port is redirected to the Firewall wan_IP 192.168.0.2

We need to redirect all the external traffic through 1433 TCP port to PC. Can you help us to configure the firewall-side?

Thanks in advance

If the 1st router has static route you can do a more advanced way of forwarding.

Or to double NAT make NAT rule for Virtual Server

incoming WAN of USG20

External 192.168.0.2

internal 192.168.9.100

port TCP 1433

Then a firewall rule from WAN to LAN for that port

Thank you, we have created a NAT Rule …

External IP - 192.168.0.2

Internal IP - 192.168.9.100

And create a Policy …

But cotinues closed …

Thank you

Your firewall Policy is wrong needs to be the zone your server is on like LAN1 not Zywall

Does your ISP allow port 1433 ?
