LAN systems not resolving IP to hostname

(1/2) > >>

I'm running a 2310 with a basic DNS/DHCP LAN configuration. I'm able to access systems using host name over NFS OK, but I also use VNC for remote desktop management. The host name is not resolving in VNC, forcing me to use IP addresses which is a hassle.

Is there a switch or configuration in the router to force DNS resolution, or am I going to have to configure a dedicated DNS server so that this may work?


* What Hardware version is your router? Look at sticker under router.
* Link>What Firmware version is currently loaded? Found on the routers web page under status.
* What region are you located?
Internet Service Provider and Modem Configurations

* What ISP Service do you have? Cable or DSL?
* What ISP Modem Mfr. and model # do you have?
Router and Wired Configurations
Some things to try: - Log into the routers web page at Use IE, Opera or FF to manage the router.

* Turn off ALL QoS or Disable Traffic Shaping (DIR only) GameFuel (DGL only and if ON.) options, Advanced/QoS or Gamefuel.
* Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual or under Setup/PARENTAL CONTROL/Set to>None: Static IP or Obtain Automatically From ISP.
* Enable Use Unicasting (compatibility for some ISP DHCP Servers) under Setup/Internet/Manual.
* Turn on DNS Relay under Setup/Networking. Link>Finding Faster DNS Addresses using Name Bench
Is Local Domain filled in under Setup/Networking/Router settings if you have this option on this model router? Local Domain name should be the same and your workgroup name which should also be the same on each client PC.

I mainly use IPs when working with most of my networking...

Would a external network switch help with this maybe?

Hardware version C1 FIrmware 3.01 USA

TWC is my provider, OpenDNS is my DNS service.

Motorola SB6141 set Honor MDD IP Mode. One IP address has been leased by CPE and is assigned to the router.

QoS is disabled already.

Advanced DNS services is OFF by choice to use OpenDNS.

Use Unicasting is enabled, same with DNS relay.

I use a Gbit 10 port switch to eliminate any bottle-necking the router may cause. I've ran into that issue with many a router and have been forced to put fast switches in. I've ran MikroTik routers on this network without issue but was forced to switch to this router for other reasons.

I ran a NSLOOKUP on this terminal after changing the local domain to the workgroup name. The last entry comes up with the local system name and workgroup name, and shows the router's WAN address.

No change after the tweak.

I guess like most routers of this price category your model only supports DNS relaying and distributing DNS server addresses to LAN clients via DHCP (either its own LAN interface address when configured to work as DNS relay or otherwise the addresses of external DNS servers either received dynamically by your ISP during Internet connection setup or configured manually if you don't want to use your ISP's DNS servers). And may be it supports DynDNS to register its global WAN IP address with a DynDNS provider of your choice.

But that's it. It will probably not support local name resolution by establishing local DNS zones for forward and reverse lookup of the names and addresses of your LAN devices within a local domain name of your choice (e.g. "homelan.local") including dynamic DNS registration for your LAN devices required due to the dynamic address configuration via DHCP. To provide this you probably have to install a dedicated DNS server hosting your local zones and configured with DNS forwarders (either your EBR-2310 when configured as DNS relay or external DNS servers) for resolving names in the Internet.

With a static IP configuration of your LAN devices (at least those you want to resolve by name) you can also work with a HOSTS file distributed amongst all relevant LAN devices which shall be able to do local name resolution.
