Virtual private networks / Re: IPSEC site2site (new connection mode) extremly slow

« on: March 13, 2024, 11:07:04 pm »

Actually that did the trick.
I've set it to 1300 (which is in my opinion pretty small) and it works perfectly.

Shoudn't I limit this normalization to traffic between those networks?

« on: March 13, 2024, 07:35:25 pm »

I don't see the problem.
perf3 from firewall to firewall shows no problem and I have the full bandwidth, but as soon as I want to use any service like file-transfer, remote-desktop, ... the connection is EXTREMLY slow.

Any hint where I could take a look?

I have to do a one-eighty...

I used iperf now it it shows absolutely no problem... I have all the bandwidth that is available.
I don't know where my problem is.

I'm using remote-desktop from a Mac on site B) to a windows machine on site A).
It is very laggy and slow. Unter "Connection information" it shows a bandwidth of around 4Mbit.
As soon as I open a openVPN roadwarrior-connection from my Mac on site B) it shows 30Mbit.

a) My Mac does something strange
or
b) opnsense somehow slows down data while routing.

Unfortunately I did not use iperf3 as I'm not sure how to use it.
My ipsec-VPN is policy-based, so the is no interface to bind on.

How do I use iperf without an ethernet-interface?

Sorry, I forgot to mention:
The CPU is more or les idle all the time.

The "slow" opnsense on site B) is a Celeron J4125 Quad Core while the "strong" opnsense on site A) is much larger...

Virtual private networks / IPSEC site2site (new connection mode) extremly slow

« on: March 12, 2024, 09:16:02 am »

Hello guys,

I have a policy-based IPSEC-tunnel between two networks which is extremly slow.
Site A) has a 100/100Mbit sync fiber-line
Site B) has a 400/50Mbit async line

I'm currently reaching 4!!! Mbit via my VPN-tunnel.
It is only related to IPSEC-VPN. When I use a openVPN roadwarrior connections everything is fine.
The log files do not show any errors or warnings.

My settings are quite basic:
Settings:
Proposals: aes256-sha512-ecp521 [DH21, NIST EC]
Version: IKEv2
MOBIKE: enabled
DPD delay: 10s
Pools: nothing

Authentication: Public key

Children:
Mode: Tunnel
Policies: enabled
Start action: Start
Stop action: Start
DPD action: Start
ESP-proposals: default
Rekay time: 36600

I also tried to enable IPsec normalization with max MSS of 1350 (as I read this on several forums).
The CPU is more or less non-stop idle.

Statistic IPsec-Interface (enc0):
mtu: 1536
received-errors: 0
dropped-packets: 0
send-errors: 0
collisions: 0

Actually I have no idea why it is that slow.

General Discussion / NAT portforward for complete subnet

« on: September 26, 2023, 07:22:23 pm »

Hey guys,

I want to redirect a port for a complete subnet.
e.g.
10.10.0.4:1234->10.10.0.4:44444
10.10.0.8:1234->10.10.0.8:44444
10.10.0.10:1234->10.10.0.10:44444
...
So destination and target is always the same. Only the port is changed.
Is there a way to prevent many manual entries?

General Discussion / Lets Encrypt Problem with multiple public IPs

« on: July 02, 2019, 01:17:10 pm »

Hello guys,

I have the problem, that Let's Encrypt is not working with multiple public IPs.
I'm using haProxy on our external server IP (xxx.xxx.xxx.68) but let's encr. is calling out with xxx.xxx.xxx.66

How can I force let's encr. to use another external IP to make the requests?

19.1 Legacy Series / Re: Installer hangs at "Select Task" on Hyper-V Generation 2 VM

I could manage to install if by booting in legacy mode, not uefi.

Hi guys.

I have exactly the same problem but I‘m not even installing on a virtual machine.
I have a clean and brand new hardware here. As soon as I‘m reaching the guided installation the installer hangs.

General Discussion / ipsec Net2Net to ipfire

« on: September 28, 2017, 09:25:37 pm »

Hi guys,

i would like to connect an opnsense to ipfire by ipsec RSA.
Is there someone who maybe has an step-by-step instruction what to take care of?

How can I import the CA from ipfire (pem-format) ?
How can I export the cert from opnSense so I can import it to ipfire?

THX

Hallo zusammen,

ich möchte gerade einen ipsec tunnel zu einem ipfire aufbauen (RSA).
Hat jemand zufällig eine Anleitung auf was man achten muss?

Wie importiere ich z.B. das CA vom ipfire ?
Wie exportiere ich das opnSense-Zertifikat zu ipfire?

Danke
