Multiple IP addresses
Each network card in the NetManager can have multiple IP addresses. These can be on different IP address ranges.
This is useful for:
- Replacing existing servers with a single NetManager, but you want to retain the same IP addresses
- Future expansion if you may need to separate out NetManager services onto separate servers as your use grows
- Port Mapping a port which is already in use (e.g. if you want to give remote access to multiple webservers, but are unable to use Reverse Proxying
- Port Mapping whole addresses to internal ones
Adding extra IP addresses to a network card is done is the same way as setting the first IP address. Use the Configure interface addresses section of the Console Menu.
Caveats
- You cannot have the same IP address range on different network cards
- You cannot use NAT between two ranges of addresses that are on the same card
