Hello,
I have changed the RB951G-2HnD’s default IP address from 192.168.88.1 to 192.168.88.254. After changed it’s IP address, the computer cannot outgoing to Internet. The computer can connect to the router (192.168.88.254) only.
Does there any user have experience to resolve this issue?
At this moment, I just keep the default address (192.168.88.1), Internet is normal.
Thank you,
Insure you change the gateway on the PC. The dhcp server settings on the router may need to be changed. That may require “Repair the connection” on your PCs.
/ip dhcp-server network
print
Hello,
Thank you for your answer.
Actually, I have also changed the DHCP range in the router. After apply the change, I have release and renew the IP address of PC to retrieve the new gateway.
But, it still cannot access to Internet.
Then you should post the following
/ip address
/ip route
/ip dhcp-server
/ip dhcp-server network
/ip pool
/ip firewall nat
/ip address = 192.168.88.118
/ip route = 192.168.88.254
/ip dhcp-server = Enabled
/ip dhcp-server network =
/ip pool = 192.168.88.101-192.168.88.120
/ip firewall nat = Enabled
(as the screen captured attached)
I should have been more specific. You should post the following
/ip address print
/ip route print
/ip dhcp-server print
/ip dhcp-server network print
/ip pool print
/ip firewall nat print
Does these are the script? If yes, how to capture the running result of these script?
The solution in your case is easy. If you do not understand what I am asking, don’t change it.
May be let me ask in this wait, how can I paste this script in the MiktoTik to execute and get the result?
/ip address print
Finally, I found the terminal to key in the command (Excuse me, I am very new for MikroTik, just start to play for 2 days). Here below are the result of each query:
[admin@MikroTik] >> /ip address print

Let me refresh my question, my Mikrotik box cannot let the computers access to Internet after change the default IP (192.168.88.1) to 192.168.88.254.
Thank you,
I recommend removing the assignment in “/ip address” and enter a new assignment. Don’t edit the address. It won’t change the stuff needed to route the new ip address. Do the same with the dhcp server. Remove it and set up a new one after the “/ip address” change.
Be careful tho. Removing the address while using it to connect to the router will cause a disconnect and you will be unable to connect to the router using that ip. I use the serial port for stuff like this.
Hello,
Thank you for your reply.
Just have change the IP address to 192.168.88.254 as the screen captured below. Also still cannot access to Internet after change.
Did you change the dhcp server and repair the network connection?
May I get more detail for the quoted “Do the same with the dhcp server. Remove it and set up a new one after the “/ip address” change”?
Since, I don’t know how to do it.
Thank you,
Remove the old dhcp server.
/ip dhcp-server
remove X
Relace X with the line number of the server for that network.
Set up the new one.
/ip dhcp-server
setup
Can I do this by WinBox’s GUI?
Yes.
Do I just disable the DHCP server by WinBox?
No. Remove it by highlighting the dhcp server entry, then click the red ‘-’. Click “DHCP Setup” and answer the prompts.
