My network has grown and I feel I should start segmenting my /22 LAN subnet. I bought a 4-port nic for my Mikrotik and plan to assign each nic its own subnet and DHCP pool. Problem is I have some clients with static addresses all on one /24 subnet that will now be spread among five nics. Is there a way to do this without assigning all the fixed clients new addresses? In other words, can addresses from one subnet be on several interfaces?
Cameron
Not really. Addresses from the same subnet have to be on one interface.
There are some hacks and exceptions (e.g. using proxy-arp when connecting via PPTP to get an IP address from your local LAN or the like) - but don’t do that - it’ll give you lots of headaches in the long run…

Could it be accomplised with OSPF?
Cameron
No - it’s just a fact that you cannot use ip addresses from the same subnet on different interface in one machine…

OK, thanks. I guess it’s time to start visiting clients.

Good sales strategy anyhow - to show up from time to time
