[solved] pfSense (2.6.0 & 22.01 ) is very slow on Hyper-V
-
And you are also seeing it specifically between VLANs on hn(4) NICs?
-
@stephenw10 Good day! In the pfSense VM, the interfaces are not associated with VLANs and there are no VLANs defined. From pfSense's perspective, it is working with native hn(x) interfaces.
Hyper-V's vSwitches are all untagged. All VM vNICs in HV are untagged.
VLANs exist past the physical uplinks in the Physical Switch.
-
Decision: do not use hyper-v as virtualization platform ))
Better try Proxmox VE (open source) -
@bob-dig said in After Upgrade inter (V)LAN communication is very slow (on Hyper-V).:
It wouldn't been the first time I had to install pfSense fresh from the get-go after a new version. Whatever my usecase is, it might be special...
So I guess "This is the Way".Wasn't the way, creating a fresh pfSense-CE-2.6.0 sadly changed nothing.
If of interest:
-
@bob-dig yep. Thx for validating. 2.5.2 is fine, use that till they resolve the issue.

If netgate does, they seem to care only for azure and we all know since the exchange debacle, that the MS Cloud is not the same as MS's server products... So my hopes are rather low on this. Might have to try with DDA once again.
-
@bob-dig Or we switch to OPNsense which is working ok on the same system where pfSense is not working ok.
-
@dd I couldn't even install OPNsense on hyper-v not long ago, you had to do a trick, and those guys want to use the normal FreeBSD too.
I am stuck, if DDA is not going to work. I have hard time to change my firewall Distro but even more changing my Homserver OS...
-
@bob-dig They have new version 22.1 which is based on FreeBSD 13 and it's working ok. I have tried it. I think that problem with pfSense 2.6 is because it's based on FreeBSD 12.3. Same problem is with pfSense 2.7.0-DEVELOPMENT which is on FreeBSD 12.3 too. I think, fix will not be available for longer time but they must something to do because now is not pfSense 2.6 (and Plus) useable on Hyper-V.

Huh? 22.01 is using 12.3 same as 2.6

@johnpoz We talked about OPNsense.

Thanks for your heads-up regarding OPNsense and FreeBSD Version. But there are many people using the newest pfSense on hyper-v, they resolved their problems it seems, although I don't know what they are exactly doing with it. If you only use it as a firewall and not as a router, that would still work here too or lets say for me at least, your WAN-Speed was and is also affected.
So why is it so different, really making no sense to me.

I don't think so, we are not paying them and hyper-v isn't used much anyway, so... no.
-
Are you able to test FreeBSD 12.3 in a similar config?
-
@stephenw10 I can't. Is in the current release this already patched? I can't tell for sure, would be helpful to know.
-
No, that patch is not in 22.01 or 2.6.
https://github.com/pfsense/FreeBSD-src/tree/RELENG_2_6_0/sys/dev/hyperv/pcib
It's not yet in 22.05/2.7 either.

I can 100% confirm this, tried it myself. I could also enable all offloading there.
This is from a VM with 4 Cores on another VLAN (and host).
What I had to do on both is disabling VMQ in the virtual NICs in hyper-V, otherwise there were some error messages in the console.
So no problem with FreeBSD 13 on Hyper-V (Server 2022) with the other thingy.

Can anyone seeing this test FreeBSD 12.3 directly?
This could be a simple fix if it's something we are setting in pfSense. Though I'm not sure what it could be.

Just did a simple test
First screenshots shows 2 Windows VMs connected through pfSense 2.6.0(fresh and clean install), all running on Hyper-V.
Second screenshots shows 1 Windows VM connected to a clean FreeBSD 12.3 Install, all running on Hyper-V

Do you see the same thing using
iperf3 -c 192.168.189.10 -Ras you do if you run the client on 192.168.189.10?That opens the states the other way so it would be interesting to see if it fails in the opposite direction.

Dammit, if I only knew about the -R thing earlier.
