ip route or route alternative to ip masquerade

Hi All,
Basic home network I have attached a small diagram.

Situation is, I always use iptables to masquerade the internet connection (wlan0) from the server to the client

On the Server, this works.

iptables -A POSTROUTING -t nat -o wlan0 -j MASQUERADE

However I am trying to learn route or ip route and I am looking to route the internet packets from the server to the client, using the "route" or "ip route" command.

Below are the details:

Server Route Table:

route -n

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface   U     0      0        0 wlan0   U     0      0        0 eth0     U     1002   0        0 eth0     U     1003   0        0 wlan0         UG    0      0        0 wlan0

Client Route Table:

route -n

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface   U     0      0        0 eth0     U     1003   0        0 eth0         UG    0      0        0 et

Added this to the client and could not ping

 route add -net netmask gw

Sorry I am confused .....

Can someone help?

in the side of the server:

iptables -t nat -A PREROUTING -p ALL -i wlan0 -j DNAT --to-destination
iptables -I FORWARD -p ALL -i wlan0 -o eth0 -d -m state --state NEW,ESTABLISHED -j ACCEPT
iptables -I FORWARD -p ALL -i eth0 -o wlan0 -s -m state --state ESTABLISHED -j ACCEPT

Best regards
