NetCom has own NAT table. You can share your Internet (WAN) connection with other computers in your network. NetCom NAT works like showed on diagram:

       For example you'r network topology and configuration equal to represented on this diagram:

If you want to allow access to the Intenet for workstations with addresses 192.168.0.12 and 192.168.0.14, do the following:

1. ALLOW ALL

Create rule to allow all network traffic from all to all - (it must be always last item in rules list):

Packet action equal to Allow

2. 192.168.0.12

Create rule with allowed access for 192.168.0.12 from internal to external network:

Packet action equal to Allow

Packets direction equal to Incoming (or Outgoing)

Protocols equal to Any IP

Source IP equal to 192.168.0.12

Destination IP NOT in range 192.168.0.0 - 192.168.0.255

Add data about packet to the NAT table [Enabled]

Replace source IP with: [Enabled], Automatically [Enabled]

Replace source Port with: [Enabled], Automatically [Enabled]

3. 192.168.0.14

Create rule with allowed access for 192.168.0.14 from internal to external network:

Packet action equal to Allow

Packets direction equal to Incoming (or Outgoing)

Protocols equal to Any IP

Source IP equal to 192.168.0.14

Destination IP NOT in range 192.168.0.0 - 192.168.0.255

Add data about packet to the NAT table [Enabled]

Replace source IP with: [Enabled], Automatically [Enabled]

Replace source Port with: [Enabled], Automatically [Enabled]

4. CHANGE RULES ORDER

You must change order of rules to this:

1. 192.168.0.12 - allow access to Internet;

2. 192.168.0.14 - allow access to Internet;

3. ALLOW ALL - needed for normal work of Internet connection and local network.

5. ENABLE FILTERING

Select both adapters for filtering (internal and external).

Note: if you use for Internet connection PPPoE, VPN or DialUp - you must select WAN-interface as external!

At this moment filtering started.

That's all...

NOTE:

       On client computers address of DNS-server(s) must be defined!

       Some firewalls can drop these NATed packets. Not recommended use other firewalls on the same machine with the Routix NetCom.
