hello guys

so i got DIA from one of the ISP’s around here

and they got the cercet to my location and every thing fine

so they toled me to configure my static ip as point to point ip wich mean

192.168.1.1 <— my ip
192.168.1.2 <---- Getway

so i add the ip’s to the address from ip like these 192.168.1.1/30
and then i went to ip → route and add the getway 192.168.1.2 to the 0.0.0.0/0 dis address

and then i went to ip → firewall → nat

then add a nat

wich got only a out interface for the DIA port in the mikrotik and from action i puten it to misquarde

then i went and done the dns and the dhcp

every thing tell now is fine

i can ping the getway and my isp can ping my ip

the problem is i ca’nt get any internet from the link

even thu im using the isp static dns and google dns

is there any else to do ather then what i done up ?

btw my isp configured a nat on the local address to go on the static one

are those ip’s the actual ips?
if yes it appears that they are doing the natting not you.

btw Usually most of the time, the Lower the number is the carrier.
most case’s .1 carrier .2 CE

btw my isp configured a nat on the local address to go on the static one

So they are 1:1 natting the local ip to a Real one. Then you dont need to NAT that ip.just leave the default route there

actuly i found the problem


i went with the static ip configration

when i put the ip like these

62.1.1.1/31

on the subnet 31 it don’t work @ all

i can ping the getway my isp can ping my ip but no internet

but when my isp change it to

62.1.1.1/30

it works fine with the same config on the main post

i don’t know whats the problem with the sub 31 as my isp made me like 5 diffident ip but the problem is there all the time with that sub

so i relley don’t know how to fix these issue
