(Alzirr) LBB & DKB Banking DNS Failure

[skulblakka 0]

Hi there,

I noticed since a couple of weeks that a couple of online banking websites can't be resolved using the DNS set by Eddie. Connected to Alzirr I can see that the DNS is set to 10.8.214.1. The domains in question are "lbb.de" and "banking-dkb.s-fints-pt-dkb.de".

Using nslookup gives the following results using the VPN DNS:

> nslookup banking-dkb.s-fints-pt-dkb.de 10.8.214.1
Server:  UnKnown
Address:  10.8.214.1

DNS request timed out.
    timeout was 2 seconds.

    timeout was 2 seconds.
*** banking-dkb.s-fints-pt-dkb.de wurde von UnKnown nicht gefunden: Server failed.


> nslookup lbb.de 10.8.214.1
Server:  UnKnown

DNS request timed out.
    timeout was 2 seconds.

*** lbb.de wurde von UnKnown nicht gefunden: Server failed.

The same using the public Google DNS (while still being connected to Alzirr):

> nslookup banking-dkb.s-fints-pt-dkb.de 8.8.8.8
Server:  dns.google
Address:  8.8.8.8

> nslookup lbb.de 8.8.8.8
Server:  dns.google
Address:  8.8.8.8

Address:  195.140.126.64

Changing the DNS server of the tunnel interface to the Google DNS allows connecting to the URLs which means there doesn't seem to be any blocking from the hosts going on.

I also tested using Andromeda which seems to work indicating that the issue might be with Alzirr specifically:

> nslookup lbb.de 10.9.22.1
Server:  UnKnown
Address:  10.9.22.1

Nicht autorisierende Antwort:
Name:    lbb.de
Address:  195.140.126.64

I hope someone can figure out what is going on as Alzirr is one of the servers with the best connection for me
