Routing public ip block to existing another subnet

RouterOS General
1

I am very new to microtik.
I am using RB2011uas-2hnd with 10 Ethernet port. my setup is simple

ip block provided by isp 185.211.xxx.96/30

WAN = eth port 4 with public ip 185.211.xxx.98/30

lan= eth port 5 with private ip 192.168.0.1/23 (masqueraded)

Default Gateway is 185.211.xxx.97/30
working good from my local lan.

recently i got 6 public ip address 185.222.xxx.184/29. and i want to route this ip addresses to some dedicated clients. my isp told me that they have routed this ip block to my existing 1. but i could not work them out.

what i did
i put first ip of this block 185.222.xxx.185/29 to a interface eth 6 of my router. configured a pc with 185.222.xxx.186/29 gateway 185.222.xxx.185 and connected to my router in port eth 6 . but no luck.

trace route result to 4.2.2.1
1 <1 ms <1ms <1 ms 185.222.xxx.185
2 <1 ms <1ms <1 ms 185.211.xxx.97
3 * * * * requested timed out
4 * * * * requested timed out

Now should i ask my isp again to route this ip block or i need some other configuration?

Please help. Thanks in advance.

First, you should add the addresses given to you on your WAN interface. That’s where you connect to your ISP.
Secondly you can use netmap to do what you want http://wiki.mikrotik.com/wiki/Manual:IP/Firewall/NAT#1:1_mapping

The setup you describe should work fine with no NAT. It sounds like there is a unicast routing issue either at the ISP or on your router. What happens if you traceroute from somewhere else to your IP block. Do you see the packets making it to your router?

Do you have an firewall rules in the forward table that may be blocking things? What happens if you run the same traceroute from the mikrotik specifying the src-address of ether6?

/tool traceroute src-address=185.222.xxx.185 4.2.2.1

If that doesn’t work I would ask your ISP again if they are routing the 185.222.xxx.185/29 block towards 185.122.xxx.98.
