Port Forwarding stopped working after upgrading to 2.8.0

comet424

@stephenw10
ah ok,.. i figured maybe there was another type style panic where its panicing and bricking the dns as when you reboot it doesnt cure the issue..

so im currently running that setup above i disabled the vpn interfaces. and it takes a long time took like 5 min for it for it to take affect when i disabled the 2 interfaces..
and i disabled rules vpn so only works through wan.. and pfsense currently can ping

so i currently updating my apps in unraid as i wasnt able to it would drop out and then pfsense cant ping till i restore

as sitting for 1 hour didnt not fix the dns issues either (with the lan port disconnected..)

this here is the dns lookup of google.. its slow due to unraid is updating and maxing out my internet... but it is also this current setup

so i restored file
i disabled the 2 vpns interfaces
i disabled the LAN rules for vpn and * for all the lan to go out the wan
in the dns resolver i set incoming and outgoing to ALL and i disabled the dnssec as i using the lancache for windows updates etc.. so i left it in for now

so i currently testing that ill do that again when it fails.. or when i re do the vpn
but this is currently what i starting from... ill get back to u when if anything fails
dns lookup1.png

and i not sure how to check vpns for the FQDN ill have to look up what FQDN is ive see that name before

comet424

so i looked up what that FQDN so thats like the domain names

so for my
WAN site to site to my sisters Pfsense i use a domain name
VPNS to connect to the PIA is also domain names

none use ip address's in the vpn settings

comet424

@stephenw10 so i had issues again with running WAN it fails till i restore the configuration i have

here is the dnslookup and ppoe etc
dns lookup wan.png
dns lookup 2.png dns lookup 3.png dns lookup 4.png dns lookup 5.png

now here is when i do a restore of the config file and i dnslookup

Ok so VPNs won't be able to connect if the servers are all defined as FQDNs and DNS fails.

What are 10.0.0.241 and 10.0.0.243?

You have 1.1.1.1 configured as a DNS server in System > General Setup?

When DNS fails it appears the system no longer has any DNS servers available other than Unbound on localhost. If Unbound is in forwarding mode that will also fail if it has no servers to forward to.

comet424

@stephenw10
so the 10.0.0.241 and 243 is just for the VPN so in general.

i removed that 1.1.1.1 from the WAN_ppoe and also had at none in general setup..

and at the point of testing the wan setup i had deleted all 3 of those dns.. it soly relied on the default like new no dns options under general setup..

so the test setup i mentioned yesterday where i disabled vpn interface.. i also deleted all the dns under general setup so it was a fresh slate

so if i restore delete the dns's under general setup disable the vpn interfaces set the rules to just lan to go out the wan... all setup in the first few mins of a restore that seems to be fine...

but when fails is what you saw in the screen shot.. if you need new screen shots let me know...

as pfsense doesnt use the vpn as internet though if uses the default where i specify use wan_ppoe under the routing section

stephenw10

Was Unbound still set to forwarding mode? It needs to have some external servers configured to forward to in that case.

comet424

@stephenw10 so if you mean the host overrides?

where i have dnssec turned off

and the host overrides point to 192.168.0.32 (lancache)

and the lancache then points to 1.1.1.1

ive also tried pointing to the pia vpn dns and the nordvpn dns

but doesnt help

ive also tried where i re enable the dnssec deleted all the host over rides.. plus the custom options as you seen in my text file to the my one drive link.. and it didnt solve nothing a reboot still wouldnt let pfsense ping doman names just ips and i have enable forwarding mode turned off

comet424

ill re do the tests

so to double check when the Enable Forwarding is checked it uses the DNS's under general setup

and if there is no dns's and you have the enable forwarding checked then there are no dns's and it cant work correct?

and if so ill re do the test

current test i doing is
of the vpns turned on and forward enabled the host overrides... and when my internet fails ill do that dnslookup and post the info

stephenw10

OK if Unbound was not in forwarding mode when this was taken:
https://forum.netgate.com/assets/uploads/files/1754407237097-dns-lookup-wan.png

Then Unbound was failing to resolve at that point. Check the Resolver logs for errors. You can also increase the log level to give more detail on individual queries.

comet424

@stephenw10 that i dont remember

but also if i do have forwarding checked off.. how does wan work when i dont have the 1.1.1.1 in general setup pointing to wan_ppoe

cuz i find everytime i add that it leaks the 1.1.1.1 into the vpn

to seperate it wan and vpn
do you just have the general setup point to the 2 pia vpn

and on dns resolver set all for incoming and just outgoing to 2 vpn interfaces..

and then wan will do its own thing ??

and under system logs do i set it to Formated or Raw .. its set at general loggin options.. to get that more detailed logs

and thanks for the help and patience so far.. i also learning alot too at same time

stephenw10

There's no way you can have all DNS queries run over the VPN if the VPN servers are defined as FQDNs which require DNS to connect.

If you don't have forwarding enabled Unbound resolves directly against the DNS root servers. It can do that across any route.

If you want to avoid DNS "leaks" from clients using one of the VPNs it's usually best to pas clients different DNS servers to use via DHCP and then route traffic to those over the VPN. You can also then add block rules to prevent any other DNS traffic leaving over the WAN directly.

Doing that means DNS from pfSense itself can be left as default because clients being routed via the VPN won't use it. But it would also mean those clients don't use the overrides and hence the lancache.

An alternative would be so set the DNS behaviour in general setup to 'use remote, ignore local'. Then pfSense itself will use the defined external servers and you can allow VPN clients to use Unbound with the overrides. Unbound itself should be set to only use the VPNs for outgoing queries in that scenario.

@stephenw10 so internet lasted a few hours then went down again.. when my vpn goes down or 100% packet loss it just takes out the wan

so i did dns resolver logs when it failed.. and when i rebooted and it never fixed itself..

the dns resolver i left it as forwarding and i only had the 2 vpns selected as outgoing.. and that seemed to work wan worked vpn worked and then it just fails or what not...

i did notice i could ping 1.1.1.1 but dnslookup failed for 1.1.1.1 i left it as the general i didnt know if u wanted raw or formated..

but here is the screen shots

here i rebooted the pfsense

here is the dns logger files.. 1 is when it failed.. and the other is when i rebooted. and nothing fixed itself
dns resolver after reboot.txt dns resolver.txt

is it doing that its removing the dns servers and it cant resolve as its showing that there is no server.. and if so how can i fix this then so wan is seperate from the vpn they dont leak over to vpn and nothing fails

and is this cuz my internet is so poor its buggering up the vpn or loosing internet...

i will retest again without the vpns tommorow.... but any other tricks or a Check box to make the vpn and wan seperate and work and not fail....

i do hope when i get better internet all this issues go away

@stephenw10 my reply was before i saw your reply

ill re read what you said what to do and the use remote ignore local ill have to look that up and google too.. as right now all you mentioned kinda lost me... so i have to re read it a few times with my disylexia and then review how to fix it...

so for the dhcp i just tell it dns is 192.168.0.1 i left it simple so that covered vpn and just plain
and if you you dont use 192.168.0.1 as the dns dont u loose local domains like the server names?

ill re read your comments tommorow.. as i got a headache and trying to understand what you wrote with a headache just makes headaches work... i appreciate the help so far

and i wish there was a video i could learn from as i a visual learner...

but ill try this stuff tommorow to look it up or figure it out from google what you mentioned

comet424

so i set General Setup
just the 2 dns servers

i set the use remote dns ignore local

under dns resolver

i unchecked dns sec, left the enable forwarding, and i set the incoming all and outgoing to just the 2 vpn servers

now i going to let that run all night and see what happens....

and ill look up that other information tommorow

stephenw10

You can't DNS Lookup 1.1.1.1, it's not an FQDN.

When you have the outgoing interfaces in Unbound set to only the VPNs then it will fail to resolve anything if the VPNs go down.

If pfSense itself it also set to use only the VPN DNS servers it won't be able to resolve the VPN servers to connect to them.

pfSense itself must have access to some other DNS server. Or the VPN servers must be entered as IP addresses directly.

I would revert to a much simpler more default config and make sure that works first.
