Access internet from lan

[philipprogramm]

Hi everyone,
I just installed pfSense on my server.
I've got 3 nics but first, I only want to use 2 of them.

My configuration:
WAN
DHCP (192.168.2.44/24), connected to another router that provides internet...

LAN
Static (192.168.200.1/24), connected to unmanaged switch
DHCP-Server configured

The problem the following:
I can ping any computer in the 192.168.2.0/24 network and the internet. But I can't access any website...

I didn't change anything else until now, here is my pfsense configuration:

NAT

Firewall

Interfaces are also up...

(Guest is the unused nic)

I already tried it with different browsers and computers but always the same problem.
Actually, I am familiar with networking, but I've never used pfSense until now.

Many thanks for your help!
Philipp

How did you manage to get two IPv4 Gateways for WAN? This should not happen via the Setup Wizard and looks wrong...
First work through https://docs.netgate.com/pfsense/en/latest/routing/connectivity-troubleshooting.html

Just reinstalled it, I also set the allow local ips thing.
I went threw all the steps in this connectivity troubleshooting guide but all the described things worked...

I really don't know what the problem is...

Edit: Here is my new gateway configuration now:

[Rico]

Try to set a external monitor IP for the Gateway. Does it still show online?
System > Routing > Edit Gateway > Monitor IP > fill in 8.8.8.8
Disable IPv6 for testing, your v6 Gateway looks not working and maybe to client you are trying picks IPv6.

Now the gateway state is unknown Update: It shows online now, but I can't ping
I disabled ipv6 and tried to tracert the router on 2.1 but it didn't work, it stopped after the server. Pinging the IP works still...
Very strange

[Rico]

Try to isolate the problem.
Diagnostics > Ping : try 8.8.8.8
if this works the connectifity is okay, maybe just some DNS problem
next try Diagnostics > Ping : www.google.com

Well, I already tried that and both things work but if i want to open a website it doesn't work anymore...

I really don't know where the problem is, i can ping, traceroute all ips and websites but I can't open them in a web browser even from different machines...

[Rico]

Your client is able to ping 8.8.8.8 and www.google.com ?
Show the output of ipconfig /all and screenshot pfSense Interfaces > LAN

Finally did it.
The problem was the Disable checksum offload function...
A HARDWARE PROBLEM... I didn't even think about that.

Thanks for your fast help @Rico

Glad you have it working now.
