[SOLVED] why my dhcp client can't ping the internet

RouterOS Beginner Basics
1

It’s my first post, and also my first contact with mikrotik, so I’m probably assuming something I shouldn’t please point it to me if you see anything wrong

My setup is fairly easy, it’s a home setup, I’m just starting with mikrotik from DD-WRT

A DSL connection to which I connect with PPPoE, A DHCP server and a bunch of clients (some wifi some wired)

The problem

from the routerboard (its a RB1100AH) I can ping google alright

From any clients within the network I cannot browse or ping the internet (well it resolves the names but does not ping) as you can see

$ ping google.com

PING google.com (77.125.228.3) 56(84( bytes of data

dhcp server works because I get an IP adress alright and a route

route -n
Table de routage IP du noyau
Destination     Passerelle      Genmask         Indic Metric Ref    Use Iface

169.254.0.0     0.0.0.0         255.255.0.0     U     1000   0        0 wlan0

Here are the information so you can help me figure out what’s wrong with my mikrotik configuration

AH AH AH found my problem right after posting it

Found the problem NAT was configured but not activated

> ip firewall nat print detail 
Flags: X - disabled, I - invalid, D - dynamic 
 0   chain=srcnat action=masquerade out-interface=ether13

once I checked the (with the ! ) it works like a charm

ip firewall nat print detail 
Flags: X - disabled, I - invalid, D - dynamic 
 0   chain=srcnat action=masquerade out-interface=!ether13

Not sure what it means though

Hello!
Of course, when you have specified an operator ! in the rule masqurade worked correctly.
But you should declare your WAN interface in this rule as an out-interface.
