Murus internet sharing not working

Solution 1:

Your set up is probably faulty. A static route on the second router (connected to the ISP) isn't required.

The proper set up looks like this:

• Open Murus and hit the wrench > Static NAT

• Choose the proper LAN and WAN interfaces. In your environment the WAN interface probably is en0 or en1 and your LAN interface is en3.

• Then move the mouse pointer to your NAT group and hit the looking glass:

  

  Remove the current IP/network address (in your case 10.0.0.25/32) and add the "NAT-client's" IP address (in your case 10.0.0.234/32) or a network address (e.g. 10.0.0.0/24).

  You added the gateway's address (instead of the NATed network/host) by accident.

  Add "ALL SERVICES" to the Allowed Internet Services.

• Close the NAT window.

• In the menubar > Firewall > Interface Forwarding choose "Enable".

• In the upper right corner of Murus hit the start button (►) - just to be sure.

• Test the NAT with the client.
