Hi Frederic, Le 25/11/2022 à 22:01, Frederic Zulian via 44net a écrit : Here, in Corsica, we separate network access and applications, using the following scheme : - Dedicated routers ("TKBoxes"), which are low-cost commercial routers flashed with OpenWRT. Prices are starting at $30. See OpenWRT hardware compatibility list : https://openwrt.org/supported_devices - Raspberry Pi (and various other models) for applications only Separating network and applications is IMHO a good practice :-) Here, the TKBoxes do the tricky job of connecting to the central POPs in PnP / NAT traversal mode, and routing two separate subnets / VLANs (HamNet and public Internet). Then, the PCs and PIs hosting applications are simply configured behind the boxes, in fixed IP. I never tried to implement the "classic" HamNet with IP-IP tunnels and modified ripd on OpenWRT, but I read some things about that in the past, and that should be doable. You can also contact French 44.168 network team, and build a GRE/L2TP/iBGP tunnel with them. -- OpenWRT is some kind of "mini-Linux" for routers. It's modular, open-source, and well-supported on various hardware brands and models (including Mikrotik, HI). It's IMHO the platform of choice for ham radio networking in general. 73 de TK1BI
