Internal DNS - external domain name not resolving

Product Discussion Peplink Balance
1

I’m using a Balance ONE with multiple WAN connections using a PepVPN connection.

Everything works well except for security camera configuration in home automation.

The home automation app uses ski-chalet.com:5100 - which resolves perfectly externally to the LAN

When the same app is used internally - ski-chalet.com does not resolve

I have ski-chalet.com in the local DNS records section of the Network config pointing to the LAN IP address of the Balance

Any ideas on what I’m missing please

Hi

Reading through what you have put you say that you are pointing the internal record at the ip address of the balance. You should point the DNS record at the LAN address of the camera so that the app knows tha address of the device.

Hopefully this helps.

Hi James

I am pointing ski-chalet.com to the balance LAN in the dns list say 192.168.2.1

What I need is ski-chalet.com:4110 requested on the LAN to resolve to 192.168.2.200 (home automation server)

This works perfectly fine when outside the LAN through Port forwarding

Can you see my problem?

Thanks

ski-chalet.com should point to 192.168.2.200 and not 192.168.2.1

Thanks for your help - but there is a whole bunch of devices from that domain with different ports

e.g.

ski-chalet.com:4110 - home automation
ski-chalet.com:4111 - camera
ski-chalet.com:4112 - door station

These are all handled externally through port forwarding

Thanks

DNS resolves your domain name to an IP address. Forwarding specific ports with that IP address is not a DNS function but instead it is what determines what gets mapped to your internal devices.

Using ski-chalet.com with a local DNS record would only work for a single device such as the camera. The app should work however by configuring a unique domain name for each internal device with its internal IP address.

This worked flawlessly on a Balance 30

I can’t justify 10 domain names for each device

Their must be a better solution!

Thanks

The other option would be to not set it internally and let it resolve to the external address, it should then get hairpin redirected to the correct device based on port.

I’m suprised you had this working on the balance 30 as it isn’t supposed to work that way with DNS. Do you know what firmware you were running on the balance 30 as it would be interesting to test it and see why it was working.

Thanks
James

James - I’ve spent 12 hours+ on this and your suggestion worked immediately.

I just change the DHCP DNS Servers to Googles public ones instead of automatic and clearly it forces it out and back in to port forwarding - no more config

Thank you so much!

Glad it worked.
