Help with accessing the management server

General Discussion

Hi,

I have been fighting with this for some time and I can’t think of anything more now so hopefully someone has an idea on what to try next.

I have my internal network and setup the management server on a box with its own external IP outside of my home network exposed to the web. Everything works great with the serve outside of my network. Can connect, add clients, etc…

Form inside my network though, i cannot access that server. The name of the server is vpn.domain.com and the rest of my network is *.domain.com. All managed by cloudflare.

The odd part is that when i turn on a VPN service such as PIA I can connect to the management server from within my network…

There must something with the DNS or routing but I can’t figure it out. When i do an nslookup of VPN.domain.com from the internal network it gives the proper IP, I can ping it, but can’t access it :frowning:

Any help would be greatly appreciated.

Thanks,

Have you tried setting your DNS to Cloudflare or Google Public DNS servers ?

Yes i have set the VPN.domain.com on cloudflare. When i do an nslookup it shows the correct IP. I can ping the srrver by IP and domain so the traffic seems to be leaving thr network but maybe not the SSL traffic. Can’t fully figure it out

Is it behind cloudflare?
And second of all, how do you handle hairpin nat. (Assuming you host the server on the same network that you are on rn)

5

The DNS points to the IP on Cloudflare.

The management server is not on the same network. It is external and the network is behind a pfsense router

6

do you have any DNS or content filter on your network or device?

7

Yes a pihole server but could not see anything related to netbird in the logs

8

can you bypass that and try a clean browser ? If you can ping could still be cache somewhere

I tried bypassing but no luck. I can ping and traceroute… Nslookup shows the right IP. Really at a loss
