Web GUI crashes after upgrade from 22.05 to 23.01
-
Can we assume this only happens when you try to access the GUI over IPSec? Or is that the only way you can test it?
-
Assuming it's policy based IPSec do you have static route via LAN in place to allow that access on the remote pfSense?
-
@stephenw10 this is the only way I can test it. At the moment I don't have local access to this firewall. Once I do have local access I want to try a default config and if it works add ipsec and then packages. It will be a few weeks before I can go to the other house.
-
Do you have something behind it you could try accessing it via? Something you could remote desktop to maybe?
-
@stephenw10 Not at the moment. maybe tomorrow I can remote to my son Macbook and try local access.
Don't know if it does matter but the problem firewall is running both ipv4 and ipv6
-
The IPSec tunnel is IPv4 only though?
-
@stephenw10 yes
-
@stephenw10 Ok, local login to the firewall works without crashes. So it is the combination of logging in to the GUI through the ipsec vpn that is causing the problem.
Weird enough I can access webcams, ssh without issues.
The configuration is the same I was using on 22.05 without issues.
-
Ok, that's good info. Our devs are looking into this I'll try to replicate it...
-
@stephenw10 Were you guys able to replicate the issue?
I may be able to go to the other house this weekend. Should I try a fresh reinstall? -
I haven't replicated it yet.
Do you have SWAP enabled on that device? What size if so? Getting a full core dump from that would be useful.Steve

If you install the debug kernel with:

Updating pfSense repository catalogue... pfSense repository is up to date. All repositories are up to date.

However if you only have remote access that could be a problem.

Still failing to replicate this.
What IPSec config are you using?
What firewall rules do you have?
-
@stephenw10 I will be at the other house this weekend and I am going to try to get core dumps with the debug kernel.
As far as ipsec config, it is a tunnel between the two firewall.
Phase1: Key exchange is IKEv2, protocol is ipv4 only, auth is Mutual PSK, identifiers are the ip addresses. auth is AES 256 SHA256 DH 14, life time 31680 sec, rekey time at default 90% of lifetime.
Phase2: mode is Tunnel ipv4, Local network is my lan subnet, remote network is set to the remote network ip/24, no nat. Key exchange/SA mode is ESP, encryption is AES256-GCM 128bits PFS key group 14, life time 5400, rekey time 4860 sec.Once I get to the other house (the remote pfsense), the first thing I want to try is to access the firewall GUI of my primary pfsense through the ipsec vpn and see if it crashes or not. The two firewalls run on different hardware with different packages installed.
I will then try to get you core dumps. I will try to see if going back to a default config with just the ipsec configuration makes any difference.
Anything else I should try?
-
Do you have any special gateways/route table entries setup which refer to the IPsec network(s)? Or any other config in other areas of the firewall itself that relates to the tunnel outside of the IPsec config you described?
Things like this sort of setup:
https://docs.netgate.com/pfsense/en/latest/vpn/ipsec/access-firewall-over-ipsec.html -
@jimp yes I had to add gateways and static routes on both end points
-
Did it just fail to connect without those static routes? I assume those changes were added in an earlier version, before 22.05?
-
@stephenw10 as we discussed it is not a failed connection. The firewall reboots with a kernel fault. Yes those gateways and static routes were added before 22.05. Is that workaround not needed anymore?
-
@jjstecchino said in Web GUI crashes after upgrade from 22.05 to 23.01:
Is that workaround not needed anymore?
Maybe not. At least for incoming connections like this. In my testing here I found I did not need it to access the webgui on a remote firewall. I'm just trying to determine if that's specific to my setup. Though I doubt it is since my setup is very basic.
I haven't been able to replicate the crash with or without the static routes though.
