Strange behavior with PPPoE

ClearView

I cannot ping the LAN IP 192.168.1.1 , Google's DNS 8.8.8.8 nor can I ping www.google.com. Both my Linux and Windows clients get the same subnet mask, default Gateway, and DNS information from Pfsense's DHCP server. I can however ping all three with my any non windows computer/smart phone.

On an affected Windows client, run "arp -a" from a command prompt after attempting a ping that fails. Does it show a MAC there for 192.168.1.1? If so, compare it to your LAN NIC's MAC from Status>Interfaces.

The more I look into this the more I think it might be an IPv6 issue but even after I unchecked the "IPv6 checkbox" and do a restart I still cannot ping the firewall (192.168.1.1)

Not good! Plug in a cable. Turn off the wifi. Try again.

P.S. Can you please use the CODE tags? This really is painful to read.

I lie, I got the mac from "insert local mac" thinking that it would insert it's local mac… Not my clients mac address.

I got the correct PfSense's LAN mac though "status_interfaces"

Sorry about the mix up.

doktornotor

That still does NOT match!

The results are the same even if I plug the cilint right into the back of the Pfsense firewall. Sorry I will use the code blocks.

Turn OFF the wifi. Look, you cannot have a computer connected to two different pieces of equipment with the same IP.

That is a hidden DHCP server is what that is! Strange that it worked with the Tomato but not pfsense. That part really though me for a loop! I would have be my life that I check all the switches for such before I started. Guess I missed one.

I really appreciate you guys walking me though this. Could I send ether/both of you a case of beer?
