Hello all,

This is my first time setting up a Mikrotik router, and so far I am very impressed with it's features and wealth of options!

However, I am having a tough time getting a very basic setup up and running.

I have been provided a static IP address from my service provider. I am trying to program that IP address into the router, and am having a difficult time.

The router is an RB750, and works perfectly out of the box (using DHCP on another network).

However, when I try to use the static IP, I lose connection to the internet, however I can still ping the gateway.

Here is what I have tried (from webfig and winbox)

IP > DHCP Client > remove existing client entry
IP > Addresses > add new entry for IP address/netmask
IP > Routes > add gateway (0.0.0.0/0 dest xxx.xxx.xxx.xxx)

Am I missing something here? The router comes out of the box with NAT rules preloaded, so I didn't think I needed to mess with them; i'm not concerned with DNS just yet as that seems pretty simple to get running.

check the following


ip should be on correct interface
check nat rule in firewall
disable dhcp on wan if running


give karma if i helped you

would anything in the NAT setup need to be changed just because I went from a DHCP to Static IP on the WAN side?

I have just left NAT settings at the default out of box settings. If I factory reset the router, and use DHCP, everything works fine.

no change in firewall required

but recheck nat rule especially this rule chain=srcnat action=masquerade out-interface=ether1 ( eth1=your wan ip)
