Hi,

what i Have:

4x XDSL Bonded with MLPPP and xxx.xxx.xxx.129 - 254 /25 Network with Public IP´s
At the Moment the Network works with a Lancom Router. Great Router but not enough CPU Power.

Lancom has xxx.xxx.xxx.xxx Static Public IP for DSL an DMZ with xxx.xxx.xxx.129/25

Clients has Public IPs to : xxx.xxx.xxx.130 - 240 , Gateway xxx.xxx.xxx.129 and DNS xxx.xxx.xxx.129 Netmas: 255.255.255.128

How to do this with Mikrotik, I don´t want to use N : N Nat Mapping!
Is this possible?

Should be able to stick your .129 address on the LAN side of the RB

Connect wan side up to the DSL routers, job done

Yes Clients can Use Internet, but the Public IP´s are not reachable from the Internet like for VPN oder FTP Services.
Only Roule in the Firewall is the NAT for the Lan (10.10.100.xxx)

mistry7

Don't use NAT then

You didn't mention NAT in your original description,

I think we need more detail

Nick

Sounds more like a routing issue. Your ISP needs to add routes directing traffic for your subnet to your router and the corresponding routes need to be propagated to all of your routers for return traffic.

A network diagram and a printout of your routes will help people figure out what's going on.

Clients have Public IP, can Surf, but not reachable from the Internet.

Hi,
I got clients running with public ips on Mikrotik and they are reachable from anywhere.

On my router i've a static public ip, lets say 10.10.0.2 and gateway 10.10.0.1.
For clients i've required my isp to reserve a /28 range for me, and that /28 range has its interenet routed through 10.10.0.2 (my primary ip).
lets say i've 10.11.0.50/28 on my router (client side interface).
Now the first client has 10.11.0.51/28, and uses 10.11.0.50 as a gateway.
the second client has 10.11.0.52/28, and uses the 10.11.0.50 as a gateway and so on.

I can reach the client ip's from anywhere without problems.
hope this helps.

my isp gave the ip address as follow:
Ip: 14.102.69.2
mask: 255.0.0.0
gateway:14.102.69.1

Extra Public IP pool :
Ip series :14.102.69.33 - 64
subnet: :255.255.255.224
Gateway: 14.102.69.32
my expected config is given below: i didnt configure my mikrotik in router mode, till now i used as ap in bridge mode only.
now i want to use it as a isp router.
my isp wont support for mikrotik routers.
experts help to get out my config. issue...
Thanks in advance.
