XG DNS resolution error

Stefan Höhnemann

Hi,

 

i have a problem with DNS resolution on my XG 115, but i think it's a setting mistake.

 

VLAN 1:

Client1 - IP 192.168.10.10

DNS: 192.168.10.1

 

VLAN 2:

Client2 - IP 192.168.20.10

DNS: 192.168.20.10

 

FW Rule: ICMP, DNS, RDP allowed

 

Client1:

nslookup Client2 - non-authoritative answer 192.168.20.10

ping Client2 -> unknown DNS Name

ping 192.168.20.10 -> successful

nslookup 192.168.20.10 -> DNS 192.168.20.1 / 192.168.20.10

mstsc /v Client2 -> nothing

mstsc /v Client2 -> successful

 

What is the correct setting to get correct DNS information from other VLAN?

 

Thanks in advance for your support.

 

Regards,

Stefan

    Stefan,

    if the DNS IP is the XG interface, make sure that the DNS service is allowed on the proper zone (Administration > Device acces).

    If the DNS is located on another zone, make sure proper firewall rule is created (allow DNS traffic).

    Use tcpdump to understand what's wrong.

    Regards
