Custom DNS host entry for the client is not working as needed? XG17.5.14 and XG18.0.3

Hi,

a suggestion, you might need either firewall rule or a SD-WAN type policy. Where do you get to when you tracert  from your PC?

Hi,

I'm not sure what you mean firewall rule or a SD-WAN type policy. can you give an example.

I already have an firewall rule to have connection from 192.168.30.0/24 to 192.168.22.2 as the ping is working fine with IP address but not the host name.

My PC does not know the host name so i cannot tracert it.

Hi,

Please check your pc can actually see the XG dns. Sounds like a dns issue.

Hi ian,

What you mean my PC can actually see the XG DNS?

I have two PC as clients.

1. This two PC can ping each other by host name. (Get IP from XG DHCP)

2. This two PC cannot ping the XG host name.

3. This two PC cannot ping custom DNS host entries.

4. XG CLI can ping custom DNS host entries.

5. XG CLI cannot ping itself by host name.

6. XG CLI cannot ping the two PC host name.

Looks like the clients know only DHCP clients host name.

I already set DHCP to use Device's DNS settings.

What am i missing?

Hi ian,

Please check in below.

The dns in your XG configuration is the internal dns, it should be youR isp dns.

Could be the old DNS issue of Windows.

So you are not asking about web-server01, instead you asking web-server01.yourdomain.com, which is not the same. 

You can verify this via wireshark on your client. 

Hi LuCar,

Thank you!

I got it solved by adding web-server01.mydomian.com in DNS Host Entry for domain joined windows.

But for Linux, it has difference outcome with difference distro.
