I am unable to ping external zone IP from client PC. Public zone ip is reachable from client pc

Below is my setup information.

OS: Centos 9

System is connected with two network adapter. ens192 and ens224

ens192--> zone=public connected to Internet and it as 192.168.22.20/24 gateway: 192.168.22.1

ens224--> zone=external connected to LAN network and it as 192.168.33.100/24 no gateway

[root@localhost ~]# firewall-cmd --get-active-zones
external
interfaces: ens224
public
interfaces: ens192

I enabled masquerade on both the zones and verified the setting.

[root@localhost ~]# firewall-cmd --zone=public --query-masquerade
yes
[root@localhost ~]# firewall-cmd --zone=external --query-masquerade
yes
[root@localhost ~]#

nmcli output:
[root@localhost ~]# nmcli

is there any routing or natting needs to be done to route the external zone traffic to public.zone network adapter. any suggestion or help is much appreciated
