@Djkáťo said in Can't change LAN IPv4, "Switch port is already in used by another interface":

can shorten to 10.0.0.3 to 10.3 for pings

I pointed this out elsewhere and was pointed to:
https://superuser.com/questions/486788/why-does-pinging-192-168-072-only-2-dots-return-a-response-from-192-168-0-58

"For example, you can ping google.com in the following ways:
google.com (domain name)
74.125.226.4 (dotted decimal)
1249763844 (flat decimal)
0112.0175.0342.0004 (dotted octal)

0x4A7DE204 (flat hex)
74.0175.0xe2.4 (ಠ_ಠ) "

(the IP doesn't answer anymore, but it does try)

That's still in warranty, you should open a ticket: https://www.netgate.com/tac-support-request

@Patch said in What happens when the state table is full? <Solved>:

I'm not convinced crippling pfsense to a similar degree to your second router would help performance

I did not do it for performance, I did it to stop crashing the ATT router.

Removing the thing is great, slightly improved my latency as a bonus. I am super happy it worked in the 7100 with no problems.

@stephenw10 said in Modify Intel X540-T2 NIC To Work At 2.5GbE ?:

Yes, when you set it to autoselect it will try to negotiate a link with the other side but will advertise only 10G so it can't try to connect at any other speed.

It may still flap since it still runs negotiation. But many newer NICs/drivers actually require that to work correctly.

Thanks. I gave that a go, had to reboot for it work but autoselect now works :) However does not seem to be as reliable as just setting WAN to 10g manually. If I save a setting that causes WAN to restart, it will flop about again. I was not getting that when manually forcing 10g.

I will go back to manually setting it. Manually setting the link speed persisted through reboots anyway.

@netblues ......well it got to 24days and a bit I think...
and then:- ( see log below )
Now 24 days is a 'recent record' for me,.. but I will probably give the Draytek,.. in modem mode a whizz now... and see how that fairs...

@stephenw10
I've now been able to test 2.8.0-BETA
(build date Mon Apr 28 1:42:00 CEST 2025)

For now, this seems to have fixed the issue.

New Screenshot

The dotted line is the installation of 2.8.0.

1 - Data from the original post.
2- Data after uninstalling plugins
3 - 2.8.0 Beta

The different form of spikes comes from the pfBlocker update. There is a new cron job at 3pm fetching some data.

Well if anything changed there it's probably something low level that the OS updates could have addressed.

@stephenw10 thanks, I think I figured it out. I assigned a new interface, kept the default name of OPT3. I had to enable it though, when disabling I lost WAN immediately. I left the IP type as none and hard-coded the speed to 2500base-T. I guess I need to just wait another day or two and see what happens.

It should ask you to reassign the NICs before it reboots in the GUI.

But of you have laggs and VLANs I would just edit them in the config before restoring it.

@stephenw10

internet -- isp device - 10.100.102.0/24 -- .111 pfsense --- 192.168.1.0/24

That's what I think he means to say.

@Stef_R Can't help as I do not do VLAN and have avoided their deployment. I have so far found no good use for them.

Ted

I think I have now received enough cautionary feedback to convince me that it was an ill-conceived proposition. I will abandon the “shared” IP plan and follow better, if not good, practice. I like the alias suggestion and that will overcome my reservations about “redundancy” in rules. Thanks to all for your heads up.

I finally solved this problem - so thought I'd update this topic just in case it helps someone else !

The unstable WAN MTU problem persisted through a number of pfSense upgrades, and was still an issue on version 2.7.2-RELEASE.

The thing that fixed it was to install the Realtek drivers using -

pkg install -y realtek-re-kmod

which installed -

realtek-re-kmod-198.00_3 Kernel driver for Realtek PCIe Ethernet Controllers

and then setting the WAN MTU to 1508 (including +8 bytes for PPP overhead).

After a day of experimenting, the system seems stable, and the WAN interface MTU is 1500

It could just be the modem crapping out, yes.

Can you try a different port at the pfSense end?

Can you test putting a switch in between the pfSense WAN and the modem? That would prove which end is dropping the link.

@naiw the instructions from Vultr sound like targeted at Linux systems (ip a, /etc/sysconfig/ -> RedHat). You may ask them for FreeBSD instructions or better for pfSense.. But I don't think automatic config will work with pfSense at all.

They assign the second IP to your instance and you have to manually create an alias, as @stephenw10 mentioned.

More infos (although old, 2016): On this forum: Two totally separate IP's on WAN - how to configure on VULTR. The result was the same, create an alias.

Thank you both for the responses. This makes sense. I had not thought that ping might be disabled on the gateway. I took @JKnott suggestion to find the first upstream server using tracert. All is well again!

Any alerts/errors shown in the gui when you logged back in?

Anything in the system logs?

You don't need a leading dot for that.
