Linux cannot connect to net
-
Hi new to the forum, I apologize if I'm missing something!
I have a network with pfSense as it's gateway and am encountering a strange issue.
All Linux distros won't connect to the net, internal or external. This includes the Windows Subsystem for Linux. Using my ISPs router without bridging resolves this, so I am unsure if I have a config error in my gateway preventing anything presenting as a Linux box from getting an IP address.
I'm probably looking at this wrong consider me a noob. Any input is appreciated

I must add that it actually only affects ONE machine, in Windows it behaves normally (except wsl oddities) but if I boot into Arch or Ubuntu it fails to talk to anything

How do you have the client configured? Is it running DHCP?
Is it failing to pull a DHCP lease from pfSense?
How are you testing to connectivity? What is the failure result?

@stephenw10 Hi Steve, thanks for the reply
The PC is failing to pull a DHCP lease. When attempting to ping google I get cannot resolve unknown host error, when attempting to ping my NAS I also get resolution errors.
ifconfig shows eth0 as not having an ip address

Ok, do you see anything logged in the pfSense dhcp logs at the time?
Is Windows also using DHCP?

From internal it could be based on many points here, vlans, firewall rules and and and....
From external it must be over VPN or if you talk about your servers inside of the DMZ it is another point we should now first.
It might be sounding strange, but you should be providing us perhaps with some more informations, that we not have to "digging all out of your nose". VLANs, DMZ, LAN or 2 DMZs, who is doing the DCHP job, if more the than one, were all the others set up as a DHCP-Relay or not?
What is all installed and activated?- pfBlocker-NG
- Snort & Suricata
- lightSquid, Squid & SquidGuard
- Is there another router in front of pfSense? That must be accepting then the private IPs at the WAN, and so on.
