@orkopaede your scaling is set to disabled still..
"Receive-Side Scaling State : disabled"

@johnpoz i see... I changed it also ecn to enabled but still

Thing.. works. what you wrote before... :(
-
@orkopaede it is just an outbound nat.
In my example when pfsense sees traffic to 2.42 from 9.100 it changes the IP from being source of 9.100 to pfsense IP on that interface, in my case 2.253.. Just like what happens when your lan clients goes to something on the internet and pfsense changes the IP to pfsense wan IP (normally some public IP).
notice the states when I do that..
Now when not natting - which pfsense wouldn't do between local networks. See the states

@johnpoz okay i think i got it:
Speeds are i would say okay the 8.227 is here probably the bottle neck:

-
@orkopaede I don't see any nat happening in your states.. Notice in my states where it shows 192.168.9.100 changed to the wlan interface IP of 192.168.2.253
If you had an existing state between those 2 IPs, then the nat wouldn't happen. You need to clear any old states between those IPs and that 5201 port so that the new connection would use the nat.
But hard to believe that "nat" alone would be that much of a hit..
edit: just for grins.. Could you disable the Kernel PTI.. That for sure could be a hit on performance.. There is almost zero sort of use case where that would be needed on a firewall.. I find it unlikely it could be such a hit to only see 16mbps vs your 200.. But have a hard time coming up with a use case where you would want/need to enable that on a firewall. And it would be a hit, the level of which is hard to say.. But why have anything enabled that would hinder the performance of your box? Unless you have a very good reason to, and have to take the performance hit.
https://docs.netgate.com/pfsense/en/latest/config/advanced-misc.html#kernel-page-table-isolation-pti
While more secure, this protection can incur a performance penalty. If untrusted users do not have access to run arbitrary code on the firewall, it can be disabled without significant security risk.
-
@johnpoz I will give that a try.
For the NAT problem. I guess the nat didn't work because everything was or is allowed in the firewall rules for this interface. How would the rules have to be set here so that the NAT can still work? Allow everything except LAN interface where the 8.227 is connected?
-
@orkopaede nothing should have to change in the firewall rules, if the traffic was allowed before. But if you had an existing state, you would need to clear out those old states that were not doing nat.. Or just wait til they go away on their own on timeouts.
-
@johnpoz Okay then I'll just reset the stats or wait. I have to go and pick up my child from kindergarten anyway so.
First of all, thank you for your time and help. I'll test further tomorrow. Thank you! -
@johnpoz Finally with the last test

-
@orkopaede you can always just kill any state in the state table directly. Under diagnostics, state table.
edit:
That seems low for whatever reason.. Notice in mine it was a very small hit to the speed, compared to just lan to lan speed.. And your on an I5.. I would think that is more powerful than my sg4860.. -
-
@orkopaede yeah you need to put the nat on the correct interface for the direction of your traffic flow ;)
-
@johnpoz ok i tested it a bit further and i think it is a windows problem. I repeated the tests on a Linux PC and I always got my 200Mbit without establishing multiple connections (iperf option -P). I don't think I have to bother anyone here with this topic. ;) Thank you once again for the help.
-
@orkopaede said in Throughput from Lan to Wan:
i tested it a bit further and i think it is a windows problem
did you actually enable window scaling - all the posts you show it disabled.edit: never mind looks like you did enable it.
-
@orkopaede I don’t see in the thread that you checked traffic shaping? I’ve seen many threads where an old setting was left enabled.
-
@steveits Hi, traffic shaping is disabled on all Interface. I never touched this part of pfsense.
-
@orkopaede So i guess it is what it is... a Windows problem.
When i find the Problem i will post it here, hopefully with a solution. -
@orkopaede Hi! Run wireshark on the Windows machine and see if anything catches your eye. Also check Windows power-saving for the NIC you are connecting from. For some poorly written drivers, Windows tends to make some bass-ackwards assumptions about what "energy saving" vs "disrupting key functionality" means.
