Port 443 timeout using Netcat but is working in browser

johnpoz

@Frogg said in Port 443 timeout using Netcat but is working in browser:

DNS fwd/rev mismatch: domain.com != machinedomain

which is why what your doing is not the correct solution.. What you should be doing is dns resolution to access your machines via their local IPs vs nat reflection..

Frogg

Do you have any clue on how i could achieve something like that ?

johnpoz

Yeah a simple host override so that whatever.domain.tld resolves to the actual local IP you want 192.168.1.4 I take it.

Frogg

I added the domain name to the local 192.168.1.4 machine if i check /etc/hostname i get the domain name

But i don't think it would fix it has the domain name in the comparaison il the host xx.xx.xx.xx.rev.poneytelecom.eu reverse DNS

Or i am really missing something

johnpoz

On pfsense create a host override - your clients point to pfsense for dns right?

So whatever.domain.tld points to your local IP 192.168.1.4, and then the ptr for 192.168.1.4 would also resolve to that..

Frogg

Thanks for the help,
but i fill like i am lacking of knowledge on this part.

In network config of 192.168.1.4 (and all local machines) i use 192.168.1.1 as DNS

In the interface DNS resolver was disabled, so i enabled it and added the Host Overrides

Dig domain.com

;; ANSWER SECTION:
domain.com      960     IN      A       internetIp

Dig - x domain.com

;; AUTHORITY SECTION:
in-addr.arpa.           3600    IN      SOA     b.in-addr-servers.arpa. nstld.iana.org. 2020081164 1800 900 604800 3600

i think i am missing something to have the same result as yours

And what is that? Is that not pfsense? This only works if what your using for dns for your local network actually ends up asking pfsense.. So the host override can be returned.

If your network is using 192.168.1.1 for dns, then setup your dns records there.

Frogg

Yes 192.168.1.1 is PFSense
Maybe it require a reboot, i ll give a try

johnpoz

You said the resolver was disabled - where you using forwarder (dnsmasq) If so then the host override would be setup there and not in the resolver (unbound). Both forwarder and resolver allow for host overrides. Set the override in whichever one your using.

You only can have either or running forwarder or resolver. You can not run both listening on 53.

A reboot is not required that is for sure.. But you may have issue with local caching on the client, so you would have to flush the local dns cache of whatever client your testing from.

Frogg

Thanks again for the help!

Forwarder & Resolver (Now changed to enabled) was disabled

It seems i am using the default cache (so it should be flushed with reboot)

systemd-resolve --flush-caches
Failed to flush caches: Unit dbus-org.freedesktop.resolve1.service not found.

After reboot result is the same

any idea ?

Huh? You can not use both at the same time.. You run into a race condition.. Which one are you using? Place your host override in the one your using.. They both allow for overrides.

Do a directed query to pfsense to validate it returns your records you put in host override..

Pfsense in my case is 192.168.9.253
