Turn Ubuntu Machine with One two Network cards into a Router

I have a Ubuntu 20.04.2 laptop that i intend to turn into a router. I have two network cards one is wireless (wl01) which is connected to Internet. I have an ethernet card (enp3s0) IP ADDRESS 192.168.0.1 to which i want to connect an Access Point that can provide connectivity to other clients.

The output of /proc/sys/net/ipv4/ip_forward is 1 I then proceeded with the following commands.

 iptables -t nat -A POSTROUTING -o wl01 -j MASQUERADE
 iptables -A INPUT -i enp3s0 -j ACCEPT
 iptables -A INPUT -i wl01 -m state --state ESTABLISHED,RELATED -j ACCEPT
 iptables -A OUTPUT -j ACCEPT

However the clients aren't able to connect to the internet. They are able to ping the gateway i.e 192.168.0.1 but aren't able to connect to the internet.

What am i doing wrong here? Reading the documentation that should do it. Any suggestions.

The output of iptables dump
