Here's the problem;
I am using this device to manage subnets of Ubuntu Linux servers and Windows 10 and 11 WS connected to a Genexis P3410B Gigabit Fibre Endpoint. The embedded DHCP server on the P3410B serves hostnames and IP addresses and resolves them on its subnet 192.168.1.0/24 without issue. One of those IP,s is connected to the Port 1/WAN port on the ER7206 and its WAN port is routed to the 192.168.0.0/24 subnet on the ER7206. This is the system Status page
The LAN and DHCP is as follows;
The problem is this, the ER7206 DHCP service has the full info set BUT is unable to resolve host names to an IP address. When you attempt to ping host you get;
"Temporary failure in name resolution" on the Linux CLI
Ping request could not find host r610-1. Please check the name and try again. from a PowerShell CLI
These devices can all be accessed via SSH without issue by way of the IP address.
How do I fix this?
