[solved] Network performance problems OPNsense 10 times slower
« on: October 26, 2021, 03:05:28 pm »
I have a network problem and maybe some expert here is able to help me. I hope I provide enough information, but if more information is needed I will provide it.
It would be nice if someone has an idea?

Problem:
I want to replace an old IPFire with the OPNSense, and when trying to test the Webproxy of OPNsense I run into massive performance problems.
For now I think it is a general network and not a proxy problem.

Environment:
A simplified topology is in the attachment image.

OPNsense version: OPNsense 21.7.3_3 (amd64/OpenSSL)
Connected two Gbit networks (igb) as LAGG with VLANs on it. In this example only one VLAN is used.

I have a parent proxy out of my control (but seems to be a squid):
Code: [Select]
admintools:~$ telnet [PARENTPROXY] 80
Trying [PARENTPROXY]...
Connected to [PARENTPROXY].
Escape character is '^]'.
sdfaasfg
HTTP/1.1 400 Bad Request
Server: squid/4.15
Mime-Version: 1.0
Date: Tue, 26 Oct 2021 12:43:44 GMT
...
My IPFire is the gateway with NATing and I defined it as LAN gateway in the OPNsense.
I can not activate the WAN interface on the OPNsense yet.

Testing:

For testing purpose I tried different curl downloads. The Linux (Ubuntu) and the OPNsense are in the same vlan.

As you can see below OPNsense via ParentProxy is 10 times slower than all other tests.
Any Ideas?

tcpdumps:
I only provide the last rows of the dumps for now, but if more or special parameters are needed, please ask.
Maybe there are already hints about the problem. On the first view the OPNsense sends much more ACKs

I do not think your problem is the same.
Someone else seems to have had my problem, but he gave up and had no solution:

Re: [solved] Network performance problems OPNsense 10 times slower
« Reply #3 on: October 30, 2021, 03:47:16 pm »
I solved it.
Short explanation: dumb
Long explanation: duuuuuuuuuuuuumb ;)

I messed up the gateways. In the LAN interface the IPv4 upstream gateway was set to the wrong gateway.
Setting it to "auto-detect" solved my problem.
I do not remember if I  set it or why, it may be in the beginning where I tested to fit OPNsense in our infrastructure.
