BRIDGE two interface subnets
-
Hello,
I have a very curious situation here.
I have a box with 6 interfaces. 3 of them are configured as WANs and 2 of them as LAN and SUBNET.
The LAN CIDR is 192.168.0.0/24.
The SUBNET CIDR is 192.168.1.0/24.
In the SUBNET interface there is an unmanaged switch which is connected to just one device(let's call it DEVICE), with ip 192.168.1.254.
For reasons irrelevant to this post I cannot change the IP of the DEVICE, but it has to be able to connect to the outside world(Internet).In the SUBNET interface I have configured only the Static IP and the DHCP server.
I have bridged the two interfaces from the Interfaces->Assign->Bridges menu.
I have added a SUBNET firewall rule that looks like:IPv4 * * * * * * none
Now I can ping the DEVICE from the SUBNET interface(Diagnostics->Ping) but I cant from the LAN interface.
I have done the exact same thing to a router with an internal WIFI antenna to bridge Wifi and LAN interfaces and it worked flawlessly.
What am I doing wrong here?I have tried setting SUBNET's ip address to None but then I can't ping the DEVICE from the Ping menu.
Thank you and sorry for the long post. I am trying to provide as much details as possible

Why would you bridge that? You don't use a layer 2 bridge between two different layer 3 networks.
Just enable Internet access from SUBNET…

OK…
But how?

And secondly, if I do that will I be able to port forward the DEVICE to the outside world?

Add the proper firewall rules to SUBNET. If you have not enabled Manual Outbound NAT is should "just work." Look at the rules on LAN. Duplicate it for SUBNET.
