pfSense kicking off LAN device for trying to download from usenet.

ssmsti

I am new to pfSense but managed to get it working just fine for mostly everything in my home setup.

I have a separate server that I use to download from usenet and pfSense simply will not allow the download to start. It works fine without the pfSense box when directly connected to my isp router.

I tried everything I can research, I've watched days of youtube tutorials but no one is having this exact issue. Occasionally a download would start a few times but it only runs for about 3 seconds before the connection is severely throttled. Then the server gets booted from the network completely. I can't get a ip address assigned to the server after that and the server says that the network cable is unplugged. All other connections continue to work.

Once its kicked off I tried swapping the network cable to another port and the pfSense box is straight up ignoring it and will not give it an ip. I figure it must be some kind of kill switch built in for anything trying to make so many connections but how do I disable that? My usenet client uses 100 connections and SSL. If I disable SSL it kinda works but will still kick off the server.

Large file downloads work just fine from my dropbox.

I also tried on a completely different device and ended up with the same result.

I managed to get everything else working with pfSense but this one I just cannot figure out.

Any help is greatly appreciated!

@ssmsti A simple diagram could help us understand how the separate server is connected to pfSense as well as do you have any packages installed.

The only thing that would actively do that is Snort or Suricata in blocking mode. Even then it would normally block the remote IPs not the local devices as they are in the home_nets alias by default.
Also it cannot block DHCP so it the device cannot even pull an IP address that is something very low level. Check the logs.

@stephenw10 Thanks to the reply.

Its a totally vanilla install of pfSense with no packages installed.

What log would I check? I cant seem to notice any activity under the firewall log when it is happening.

@nollipfsense Ill do my best.

[BRIDGED ISP ROUTER 200:200:200:200]

[PFSENSE BOX 10:10:10:1]

[SERVER 10.10.10.19] [WIFI SWITCH 10.10.10.10] [PC 10.10.10.50]

I have the ports bridged in pfSense.

Any chance you have a loop on the bridge and stp is disconnecting it?

If that port is in a bridge how is the bridge configured? The bridge interface is assigned as LAN?

Check the output at the command line of ifconfig -vma.
Does pfSense also show the link as down?

If so that will be logged and may include a reason for it.
