Question about routing.

We have couple public IPs. The regular setup is 1 to 1 NAT.

I have one server that is assigned a different public IP from the pool that was given by ISP.

If I try to browse to it from any other place – it works fine. If I try to browse to it from the servers that are behind the FW – it errors out. Both have their own vlans

How/what needs to be done on the FW for servers that are inside to browse to the new server with a different public IP.

I think that process is called LAN to WAN to WAN to LAN.

    Hi @Ilya,

    Create a NAT policy as same as below, Instead LAN subnet choose "Firewalled subnets".

    Hi @ILYA,

    Along with the loopback NAT policy, ensure to have an access rule from the source zone to destination zone allowed. If the VLANs are directly configured on the SonicWall, then you can use "Firewalled Subnets" in the loopback NAT policy, else please create an address group consisting of the VLAN subnets and then call it in the NAT policy.
