Re: Relay a subnet, not being part of it

Glad to hear that you went with my first recommendation. For future requests, please state your requirements & constraints clearly... As said, it’s part of a bigger network, and my constraints as mentioned in my first post aren’t worked around, and the solution didn’t involve any change in the topo...

Re: Relay a subnet, not being part of it

FINALLY !!! I reviewed my network adapters on GNS3, changed them to "virtio-net-pci" (which is Paravirtualized Network I/O" on GNS3/macOS, created a new project with a GW, R1 and a VPCS. [*] GW has ONLY an IP (192.168.0.1) and a DHCP (192.168.0.2-254). [*] R1 has ONLY bridged ports (nothing else, no...

Re: Relay a subnet, not being part of it

I don't have any with me. I'm on holiday and didn't bring a test unit with me. My own hAP lite is on its way to me. I wonder if it's not CHR related because of my tests. Even the most basic configuration to make a bridge isn't working as it should. I will try to report that to the support, maybe it'...

Re: Relay a subnet, not being part of it

Did you try if it works without those /32 routes? And on R1 without setting routes for 192.168.0 (both network and GW)? Because of the "and" after the interrogation point, I understand that the /32 you're talking about are the routes to each other routers (to 1.1.1.1 and 2.2.2.2), the routes were d...

Re: Relay a subnet, not being part of it

But then again, as ether1 and ether2 are bridged, all traffic between PCs and GW should pass through R1 switched (not routed). I agree! Could be firewall on GW that gets in the way ... or something completely different. It's hard to tell without knowing complete configuration. Well, as requested, I...

Re: Relay a subnet, not being part of it

Above is not correct: a router needs to be addressable by clients on that subnet, so it could relay traffic. Ok. So, are you saying that all the R1, R2, Rn must have an address in the 192.168.0.0/24 subnet to allow PC to communicate with GW, right? So the only configuration to add, is a DHCP-client...

Re: Relay a subnet, not being part of it

A bridge / switch will relay any packet it receives, independent of it's ip configuration. You can assign an ip to the switch/bridge belonging to one of the subnets passing through so you could manage the router. I agree, the router, with all its ports bridged, should act as a switch, relaying ever...

So basically there are some max values for EIRP set (and for my country quite a few channels have different max values, some lower some higher).
I also have few 951G. According to your output, does it mean the min antenna gain for the range 2402-2572 is 30dBm ?
