Hello,
I've an ADSL Router with Static IP. Internet provider gave information to configure it as RFC1483 Routed ( IP, Mask, GW ) , but I need to run it in mikrotik.
I suppose I have to change configuration in ADSL route to RFC1483 Bridged , but I don't know witch kind of connection I have to create in mikrotik to make it works. I did it many times with PPPoE connection, but no in this mode.
Any help?
Thanks you
============
SOLUTION
Create new wan connection:
vpi/vci = 8/32
service: IPoA
nat: disabled
ip address: 10.0.0.2
netmask: 255.255.255.252
ip remote address: 10.0.0.1
Go to LAN Settings:
Change Lan Router IP to Public GW : 80.xxx.xxx.1
*You activate secondary IP with private IP range
Activate DHCP server and set your PUBLIC ip: 80.xxx.xxx.234 - 80.xxx.xxx.234
*Same IP in Start and End range.
If you need to set gw in dhcp server then use public GW: 80.xxx.xxx.1
After that we only need to get ip by dhcp client in our mikrotik and that's all.
Try pppoe client or DHCP client, it depends on your provider, those are the two most common methods.
There is not username/password for PppoE
DHCP client doesn’t work , I even tried to set public IP, GW and Mask manually, but it doesn’t work.
I don’t know what to do
Sorry didn’t spot you were in Spain. Are we speaking about Movistar? try pppoe-client, you only need to set these parameters:
General Tab:
interface: the one wired to the ADSL router
Dial out:
username: adslppp@telefonicanetpa
password: adslppp
Leave everything else in its default settings.
Take into account thant on the mikrotik router, you’ll need to firewall and masquerade on the pppoe-client1 interface, not the ether connected to the ADSL modem.
Yes, it’s telefonica Movistar,
It works to me with services with dynamic IP but no I’m the case ( Static IP ) . Always Pppoe status is “connecting”.
Greetings
Sorry forgot you were using an static IP, in this case you need to manually enter the addressing parameters.
For Movistar you can deduct the gw ip from your fixed IP / netmask:
Say your ip is 88.88.88.99, and your netmask is 255.255.255.192.
Launch your calculator, set in programming mode, type in your latest IP octet (99) and do an AND operation on netmask latest octet (192), then add 1:
the result in this example would be 99 AND 192 = 64 +1 = 65.
Gateway in this example would be 88.88.88.65.
Then Create Pppoe connection with Movistar credentials and stablish ip,gw,mask to Pppoe interface?
No, no need for pppoe-client nor DHCP client; just set address / netmask on IP > Addresses on the ether interface wired to the router, and set default gateway (0.0.0.0/0 dst address) on IP > Routes.
I set my ip and gw on addresses
I set gw on routes, gateway is reachable, but it doesn’t has internet. why?
I create nat rule masquerading interface, but same result.
Difficult to say without looking at your configuration.
Open a New Terminal, issue
/export
Then copy and paste the text here, change your IP /gw IP two first octets.

Are you positively sure that your netmask is /24?? It would be the first time I face a Movistar static IP on a /24 range.
If netmask is wrong, so will the gateway…
Yes netmask is /24, Even I called them to confirm it
I configured ADSL router with these parameters and it works. ( rfc1483 Routed )
I don’t know why it doesn’t work
What’s the router model? did you disable NAT when put in bridge mode?
Try setting 88.xxx.xxx.2 as gateway on the Mikrotik.
This is my actual config on Movistar Router
I set 80.xxx.xxx.2 as gateway and it doesn work.


It’s been almost 10 years since last time I touched a Movistar DSL router with Static IP and by that time I only used Zyxels 660HW (the rest were a POC).
You need to remove the current ATM connections on Advanced Setup → WAN Service, then Remove.
Then you have to create a new IPoA one: Advanced Setup : Layer2 Interface-> ATM Interface
ipoa0 8 32 Path0 UBR IPoA DefaultMode Enabled
2.- Wan Service
ipoa0 ipoa_0_8_32 IPoA Disabled Disabled
Go to LAN. Disable DHCP and set IP address as static; you should use the calculated GW here (88.xx.yyy.2/255.255.255.0).
No changes on RouterOS config (set default gw as 88.xx.yy.2).
Try 88.xx.yy.1 as GW on both modem and routeros if .2 doesn’t work.
Hope it helps.
Finally I solved it.
Create new wan connection:
vpi/vci = 8/32
service: IPoA
nat: disabled
ip address: 10.0.0.2
netmask: 255.255.255.252
ip remote address: 10.0.0.1
Go to LAN Settings:
Change Lan Router IP to Public GW : 80.xxx.xxx.1
Set right netmask ( Calculate it as pukkita said )
*You can activate secondary IP with private IP range
Activate DHCP server and set your PUBLIC ip: 80.xxx.xxx.234 - 80.xxx.xxx.234
*Same IP Start and End range.
*Set your network mask properly
If you need to set gw in dhcp server then use public GW: 80.xxx.xxx.1
After that we only need to get ip by dhcp client in our mikrotik and that’s all.
PD: pukkita thanks you for your help, you were very helpful , GRACIAS
