Filter connections from LAN to WAN

Ewon Support Ewon Flexy
#1

Hello,

I have a simple machine network that can be accessed through an ewon Flexy.
I have a new need: one server located on the LAN side of the Ewon shall access a specific webservice on the internet.

I am able to open the internet access with this help: https://hmsnetworks.blob.core.windows.net/www/docs/librariesprovider10/downloads-monitored/manuals/knowledge-base/ssh-0068-00-en-allow-internet-access-for-ewon-cosy-lan-devices.pdf?sfvrsn=824556d7_12

Now, I would like to restrict this internet access to the only public IP of my webservice.

I know I could do it with an external firewall, but is it possible to do it in the ewon?

thanks

No, not really. You can still reject all inbound traffic to the LAN with WANitfProt = 1, but once you allow LAN to WAN traffic, you would have to limit it by an external firewall or within the LAN device itself.
