There are two possible reasons:
1. You have NAT disabled but you need to enable it (packets will get lost or dropped)
2. You configured the firewall to do exactly what it does (Drop all packets which are not allowed to pass)

Thanks for your reply, will try this.
I have another concern on my DHCP:
DHCP Server: Enabled in Lan
The client and the OPNSense device cannot ping each other.

Can the client see the web interface? You may need to check your ICMP rule.

Do you provide the correct IP address range and gateway to the client?

Hi bartjsmit,
as of checking client did not see the web interface. I will try to add the ICMP rule in my device later.
I will give you update once it is done. Thanks for your reply.
Hi fabian,
Yes, the device broadcast a correct IP Address, but the connection is limited, they cannot see each other even they have acquire the IP from the OPNSense DHCP Server.
Thanks,

Hi to all Senior Support Team,
I allow all the rules also the details that you said, but problem still the same, I have no internet in my DHCP client.
Hoping for your usual support and help.
Thanks,

HiJandal,
Just to be clear; this forum mainly consists of fellow users backed up by project developers. Official Deciso support is through the website.
Have you tried a client with a static IP?

Your ruleset has issues anyway.
When I look at your rules there is no sense in having a rule to pass traffic from another source than a host, a network from lan or * here. All those entries will never be applied.
An allow any to any rule seems to exist multiple times - there is no further processing required after the first one
What is LANGW? A LAN usually does not have a gateway.
From this point of view I think there is something wrong with the routing.
