Ubuntu Server 16.04 routing issues
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}
I'm setting up my server to do all my routing. The LAN side seems to be working fine (dhcp is assigning IP and connecting) however there is no internet connection to any of the clients. But I can ping www.google.com from the server and I get a response. It seems like the server is connected to the internet but doesn't share the connection. I'm using isc-dhcp-server. Can someone help me?
Here is what I get when I run ifconfig

The LAN side seems to be working fine (dhcp is assigning ip and connecting) however there is no internet conection to any of the clients.
To give your client or guest on your LAN or NAT network access to internet, make sure that:
- Your Server can ping 8.8.8.8 or google.com
- Your client or guest can ping server gateway
Do to following:
iptables -t nat -A POSTROUTING -p tcp -s 192.168.0.0/24 -j MASQUERADE
Replace your network or just IP address of the HOST with the IP above, then from try to ping google.com or 8.8.8.8
