Fix iptables NAT on raspberry pi 4

I have a raspberry pi 4 connected to internet via wlan0 interface and want to connect clients to raspberry pi eth0 interface.
I have edited the /etc/dhcpcd.conf:
interface wlan0
static ip_address=192.168.0.98/24
static routers=192.168.0.1
static domain_name_servers=192.168.0.1


interface eth0
static ip_address=192.168.1.98/24
static routers=192.168.0.98
static domain_name_servers=192.168.0.98

I have run:
iptables -A FORWARD -i eth0 -o wlan0 -j ACCEPT
iptables -A FORWARD -i wlan0 -o eth0 -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE
and then iptables-save > /etc/iptables/rules.v4
I have enabled forwarding in /etc/systctl.conf
THE PROBLEM
eth0 interface no connection to the internet
wlan0 interface works well as long as eth0 is disabled
