Problem linking public ip's to two diferent LANS:

RouterOS General
1

Hellow all. I have MT running on a RB532A with the next configuration:
ether1 WAN 172.26.0.XXX/21
ether2 LAN1 192.168.0.XXX/24
ether3 LAN2 192.168.1.XXX/24

On the WAN interface we have 7 public ip’s provided by the ISP
172.26.0.110
172.26.0.111
…
172.26.0.116
and i want to link various of this ip’s to LAN1 or LAN2
for example:
172.26.0.114 linked to 192.168.0.114 on LAN1
172.26.0.115 linked to 192.168.0.115 on LAN1
172.26.0.111 linked to 192.168.1.111 on LAN2

I Followed the wiki tutorial http://wiki.mikrotik.com/wiki/How_to_link_Public_addresses_to_Local_ones
making this on mikrotik router:
[admin@MikroTik] ip address> add address=172.26.0.114/21 interface=ether1
[admin@MikroTik] ip address> add address=172.26.0.115/21 interface=ether1
[admin@MikroTik] ip address> add address=172.26.0.111/21 interface=ether1
[admin@MikroTik] ip address> add address=192.168.0.254/24 interface=ether2
[admin@MikroTik] ip address> add address=192.168.1.254/24 interface=ether3

Now entering commands to link 172.26.0.114 to 192.168.0.114 and 172.26.0.115 to 192.168.0.115
add action=dst-nat chain=dstnat dst-address=172.26.0.114/32 to-addresses=192.168.0.114
add action=src-nat chain=srcnat src-address=192.168.0.114/32 to-addresses=172.26.0.114
add action=dst-nat chain=dstnat dst-address=172.26.0.115/32 to-addresses=192.168.0.115
add action=src-nat chain=srcnat src-address=192.168.0.115/32 to-addresses=172.26.0.115

it works, the servers are accesible from outher networks.
And here is the problem, when i try to do the same for an ip on LAN2:
add action=dst-nat chain=dstnat dst-address=172.26.0.111/32 to-addresses=192.168.1.111
add action=src-nat chain=srcnat src-address=192.168.1.111/32 to-addresses=172.26.0.111
The resut is that the server is not responding from internet, and can’t access to internet.

Some idea about what is happening?

Only obvious things that come to mind are:

Is the gateway for your server 192.168.1.111 set to the MT box correctly - 192.168.1.254? Netmask and network set properly on this server?

Try pinging the MT gateway, next try pinging the next gateway past the MT - something on the 172.26 (I assume that your gateway is there, if not then whatever the next gateway from your ISP is) - see if that works. You can also use traceroute (linux) or tracert (Windows under command prompt) to trace to another server on the Internet and see where you are falling off at…

Just reseted the mikrotik configuration and started step by step and now is working whith the same configuration. Thanks for all.
On monday will continue testing if all works.
