Cant resolve site from internal LAN.

John Henry Vindas Carballo

Hi all,

I have a XG210 in gateway mode. Also I have a server with a site (100.100.100.4) in it and an internal DNS server (100.100.100.2) to publish the site.

I can see the site from the internet but not from the internal LAN.

I have a DNAT rule to also access the site from external sites.

I create a DNS host entry.

And I'm pretty sure no DNS traffic is blocked by the firewall.

Users have 8.8.8.8 and 4.2.2.2 as DNS in their machines, I did switch the DNS IP to our internal DNS and still can't resolve it.

I can ping the host 100.100.100.4 from the LAN.

I don't have DHCP configured in the XG.

Any help would be appreciated.

 

Thanks.

    John,

    if you are using internal DNS, make sure to create a the proper record A inside the proper zone and that computers are able to resolve "www" by name.

    Take note that "www" is not sufficient. In your internal network, computers are joined to a domain, for example test.local, so creating a www will correspond to www.test.local.

    On XG, create the host using FQDN and ping the name from XG and check if it works.

    Regards
