Client IPSec EAP VPN does not work after upgrade to 2.5release

[matyi.szabolcs]

Hi @daddygo !

Azt hittem káprázik a szemem, hogy magyarul olvaslak, vagy a google translate maradt bekapcsolva, de nem.

Igen ez az eset a termelésben történt. Előzőleg itthoni környezetben már 2 pfsense-t sikeresen lefrissítettem hiba nélkül, igaz itt ipsec nem volt csak openvpn. Már szinte biztos voltam benne, hogy nem lehet probléma. Jelenleg stabilnak látszik több további patch beadása után, de még szükség van időre a teszteléshez. A widget meg egyelőre így marad, van helyette nagios check.

Örültem a találkozásnak,
Üdv.

Az elmúlt években tapasztalatom szerint csak én vagyok itt magyar, vagyis Én sem az országban élek.
Maradj a 2.4.5 -p1 -en egy darabig nálunk több mint 200 pfSense telepítés fut kisseb nagyobb rendszereken, harmadik fél HW -in és original Netgate cuccokon is. Korai a 2.5, nálam egy Cisco UCS-C240M5 fut tesztként, de nem jó még.
Valahol majd 2.5.3-4 körül lehet váltani, de ígéretek szerint nyáron kijön a 2.6, ergo a Netgate kisérletezik velünk, hihihihi.
A fórum jó petricsésze nekik rengeteg "bug" jön elő.
Abban az esetben, ha segítség kell általában itt vagyok, sok ismerősöm van itt sok szakterületről, tudunk segíteni sok mindenben.
Örültem Én is!

+++edit:
jah a "patch" -kel az a gond, ha firssül az FW a pkg - manager felülír mindent, nem sok marad megbelőlük, tehát mindent kezdhetsz újra, inkább jelentsd a dologokat "redmine" -on:

Hi @daddygo

Köszönöm az információt!
Most vettem észre, hogy a patch nem aktiválódik.
Most mind a 8 patch ezt írja a tesztnél:

Patch can NOT be applied cleanly (detail)
Patch can be reverted cleanly (detail)

Mindegyik patch tesztelésnél hasonló hibák.

A VPN kapcsolat rendben, status oldal is mutatja az aktív kapcsolatokat. Egyedül a widget nem. Van esetleg információd melyik patch amire tényleg szükség van és melyek a nem fontosak? Tegnap amikor csak 2 patch volt hozzá adva, akkor minden rendben volt, a widget is. Ma reggelre szakadt meg a kapsolat és hozzá adtuk a további patcheket és most ez a probléma.

Üdv!

Átnéztem és nekem úgy tűnik, hogy nagyobb a probléma mint elsőre Jimp gondolta 17 perc elteltével adta ki a két patch -et és mindegyik PHP related....

https://redmine.pfsense.org/issues/11435

figyeld csak "redmine" Renato már át is tette 2.5.0-p1 -be, ami nekem erőssen azt sugalja, hogy a sok hiba miatt nem sokára kiadják a -p1 -et.

A második patch az aktuálisabb, de az sem jó

Egyébként hol használjátok az IPSec -et? Két - több iroda, cég, telephely között..?
Ideiglenesen nem megoldás az OpenVPN az most működik rendesen, vagy Wireguard, ha nagyobb sebesség szükséges..

WG -nek durva a teljesítménye, teszteltük és 6 napja fut két branch master router között.

Hi @daddygo

Az ügyfelünknek már megvolt az ipsec hálózata mikor hozzánk került (több nagyváros között). Szóval mindenképp csak ezt tudtuk használni a pfsense-ben a már meglévő kapcsolataihoz. Ez most különösen kritikus probléma volt mivel a telefon is ipsecen keresztül üzemel. Volt kiesés is míg megtaláltam ezt a fórumot az ideiglenes megoldással, hogy a pre-shared-key újbóli beadása segíthet. Utána vettük észre, hogy sem a státusz oldal sem a widget nem mutatja megfelelően az adatokat. Egyelőre most működik jól, a státusz oldal is rendben, egyedül a widget a probléma de ez most elhanyagolható. Így hagyjuk és figyeli a nagios check_ipsec.

A WG is érdekes mindenképp, igen főleg a sebesség miatt. Ezt is majd tesztelni kell és semmiképp sem hagyjuk figyelmen kívül. Használ AES-t a hardveres titkosításhoz, vagy annélkül csinálja?

Köszi az infókat!
Üdv.

Nem
a sebesség pont ezért van, mivel ezt használja
ChaCha20 + Poly1305 + https://tools.ietf.org/html/rfc7539

Yes, I have the problem with the widgets and status page also. Not sure about applying the patches. Did they work? I could not understand the rest of the thread.

Answer from just another user with IPsec problems: forget about 2.5.0 in its current state and the patches mentioned.

We had a perfectly working tunnel between our remote office and our HQ until I decided to upgrade our office site. Even with IPsec working in the evening when I leave the tunnel is down the next morning. Logs don't help, there are 500+ entries within 45min alone with some logged rubbish but without a clue to the problem.

Applying those patches didn't make any difference. Tunnel down next morning. Rebooting the device and it's up for an unknown period again.
Whatever the reason, this 2.5.0 is borked in its current state even with all patches applied as of 2021-02-25.
Sorry, netgate team. If an update brings a working system down then it is kaputt. Face it.

That doesn't match up with the symptoms in this thread, please start your own thread and we can help you figure out what's wrong with that setup. Sounds like maybe the tunnel isn't rekeying properly or the child SA close action needs set on one side to make it reconnect (especially if it's VTI)

Jim,
thanks for your offer!
Unfortunately we don't have the time to dig through this. Our fix was to rollback to 2.4.5-p1 and stick with that version. Maybe we'll have a look at 2.5.0 +1 or so.

Fair enough but if nobody else hits the same problem as you then there is little chance of it being fixed. If we don't know enough about it and can't reproduce or diagnose it, then we can't work on it.

Too bad, the last comment of this tread has been deleted. You could think of a community test - distribute the VPN credentials of the test environment to the forum participants and we will provide you with all possible dumps and logs. Really guys, I'm available. All this would have allowed your customers not to spend sleepless nights studying IPSec in the hope of finding "that" fantastic configuration that will allow their company to work peacefully. Please...

We do test it. We all use snapshots on our home edges with IPsec back to HQ, I have dozens of tunnels and mobile setup styles in my lab and am constantly monitoring and testing them with Windows, Android, and OS X clients. Others here have their own setups at home and in their labs as well. All of mine work, but there are only so many different scenarios we can test.

With all the settings possible in IPsec there are thousands of different potential configurations and client combinations. At some point we need more feedback from real-world users instead of tests in lab conditions.

As a solution, we re-entered the Pre Shared Key from the config.xml Backup file and save.

If you look at the contents of config.xml before and after re-entering the key, are there any differences? Are there any differences in /var/etc/ipsec/swanctl.conf for keys before and after changing config.xml? There should not be, but if there are, I need to know what they are.

The status problem is already known and fixed. To ensure you have all of the current known and fixed IPsec issues corrected, You can install the System Patches package and then create entries for the following commit IDs to apply the fixes:

Hi Jimp,
I had installed the patches but after I added a second ipsec site2site tunnel all tunnels are shown as dicconected in the widget. Maybe @matyi-szabolcs and @DaddyGo found a solution but I'm only able to understand english and german ;)

I tried to check some return values from the funktion: pfSense_ipsec_list_sa() like in https://redmine.pfsense.org/issues/7856 but I'm not able to do. I don't know how. Maby you can sne me a link for an how to or an documentation how I can do this and I can debug myself and help you out?
Cheers

Hi,

nope, we didn't find a solution either, unfortunately...

we just met and spoke on the same language briefly, I apologize to the other colleagues...

PS:
there are not many Hungarian speakers here on the forum
