IP Addresses

Each network card in the NetManager can have multiple IP addresses assigned. Generally however, each card will only have 1 and these would all be on different IP address ranges. Extra IP addresses can be added with Aliases.

If you have a multiple cards which are attached to different IP address ranges, then the NetManager will route traffic between those ranges (as long as the client computers have their default gateway set to the relevant local NetManager IP address), i.e. it will act as a Layer 3 router. Traffic routed through the NetManager may be firewalled.

Alternatively, you can use NAT between multiple cards which will hide one IP address range behind another.

You should NOT have the same IP address range assigned to multiple network cards.

Configuring

IP addresses need to be configured from the Console Menu so that connectivity is not interrupted. Go to option N (Network configuration) followed by option A (Configure interface addresses). You can configure main IP addresses and Aliases from here.
