The LANCOM router cannot be located in the local network with the unified firewall, otherwise the router would send the response packets directly to the devices in this network and not to the unified firewallUnified Firewall. The unified firewall Unified Firewall would then discard any further packets that belong to the same session. The same applies in the other direction. The unified firewall Unified Firewall cannot be in the network of the LANCOM router. |

1) Configuration steps on the Unified Firewall:
1.1) Connect to the unified firewallUnified Firewall, go to the menu Network → Connections → Network Connections and click the “pencil” icon to edit the settings for a previously unused interface (in this example eth3).
...
1.3) Enter an IP address from a previously unused network in CIDR notation (Classless Inter Domain Routing), which is to operate as an intermediate network between the unified firewall Unified Firewall and the separate router (in this example 192.168.99.254). Then click Save.
...
2.1) Using LANconfig, connect to the router, switch to the menu Interfaces → LAN → Ethernet ports and choose a previously unused Ethernet port off (in this example eth ETH 4).
2.2) From the drop-down menu for Interface usage, select a previously unused logical interface (in this example LAN-2).
...
- Network name: Enter a descriptive name (in this example InterINTER-NetworkNETWORK).
- IP address: Enter the gateway IP address from the intermediate network set in step 1.6 (in this example 192.168.99.253).
- Netmask: Enter the corresponding subnet mask.
- Interface assignment: From the drop-down menu, select the logical interface that was set in step 2.2 (in this example LAN-2).
...
2.9) Navigate to the menu IP router Router → Routing → IPv4 routing table.
...
- IP address: Enter the network address of the network with the unified firewallUnified Firewall (in this example 192.168.1.0).
- Netmask: Enter the corresponding subnet mask.
- Router: Enter the IP address of the unified firewall Unified Firewall in the intermediate network assigned in steps 1.2 - 1.3 (in this example 192.168.99.254).
- IP masquerading: Select the option IP masquerading switched off.
