how can i add two ip range on one lan card ?????

RouterOS General

i want to add 2 ip range on one lan card because clients more than 255 and any body can’t take a new ip because dhcp pool is empty

Assuming that you use private IP space, why don’t you just apply a larger subnet mask?

how can i apply larg subnet mask ??? to use more than 254 ip

By editing the subnet mask of the IP address on the LAN interface. Make sure to adjust the subnet mask on all statically configured clients behind it, and in the DHCP server settings on the router so that clients receive the right mask.

Edit: you should probably also read up on TCP/IP basics. http://www.ipprimer.com/overview.cfm

Try this submask!!!

128.0.0.0

Alternatively just add another IP address of a different subnet. This should allow traffic between the two subnets that the interface now has.

I have 10.200.1.0/24, 10.200.20.0/24 and 10.200.30.0/24 as subnets with my RB450G eth2 set as .1 on each network.

Just remember that if you use traffic queues for bandwidth allowance, subnet to subnet traffic may get caught in the queues.

A subnet is a way of dividing up the IP ranges. Look at the following link as a quick reference to see how many addresses are in each kind of subnet type:

http://krow.net/dict/subnet.html

So lets say you’re current LAN subnet is set to 192.168.0.0/24, this gives you an subnet with 256 addresses in it (192.168.0.1-192.168.0.254 usable), if instead you made it a 192.168.0.0/23 you now have 512 addresses in it (192.168.0.1 - 192.168.1.254 usable) and so on. In this way you can increase the number of available addresses on your LAN side.

So for the Mikrotik to add in these extra addresses you’ll need to modify the Mikrotik’s LAN subnet mask, your DHCP server’s subnetmask, and your IP Pool to take advantage of the extra addresses (I think that covers all the settings that need to be adjusted in the Mikrotik). In addition to this any devices that have static IP settings on their machines you will also have to update their subnet mask as well so that they are using the correct network and broadcast IP addresses.
