Connecting to a second office with 2 NICs in one PC
I have 2 offices next to each other, however each office has its own firewall (different manufactures).
Office A needs to communicate with Office B with one computer. In office A I have one computer with 2 NIC cards, one configured with the 0.1 network and the other with 1.1 network.
I have a physical connection going from Office B (Sonicwall) to the second NIC card in the PC in Office A.
When I go to office B I can ping office A, but when I go to office A and try to ping office B, I don't get a response.
The PC in office A is running Windows 10 Pro
Question, can this set-up work with 2 NIC cards in one PC to create the connection across the two networks?
I have tried creating routing rules in the firewall, but no success so far. I can only ping from office B, but not the other way around.
Thanks in advance

From office A I have a physical connection from X2 n the firewall configured to allow traffic from the NIC on 0.1 network.
I am trying to map a folder from Office A to Office B so we can save images from office B to office A.

I can ping this PC from Office A, but cannot ping back from office B.
Hope this makes sense

Office A is in windows server 2008 and office B is WIndows 10 Pro
Do you have any rules that would allow or deny this connection from inbound calls.
How are you connecting to the other office. I have to assume you have VPN?
If you are able to run a physical cable from one office to the other why not just bypass the firewall and connect the second nic to either side of the other network.

Correct, I don't have a VPN.
I have a physical cable going from one of the ports on the sonicwall X2 from office A going the second NIC card on the PC in office B.
I have attached an image to this question showing how the physical connection is currently.

Did you try disabling the Windows firewall on the machine that cannot be pinged ?
Like yo_bee says . . . disable firewall on Windows machine that can't be pinged. Clearly, if ping works in one direction, there's logical connectivity and it's unlikely that a physical / separate firewall would be configured to allow ping in one direction but block it in the other.

I have done a slightly different set-up.
I have upgraded the sonicwall on site B.
The 2 sites have now Sonicwall identical firewall.
I have configured X2 port on the 2 firewalls and run an Ethernet cable to the 2 firewalls connecting X2 port on both sides.
The issue now - I can ping Office B from office A, but cannot ping office B from Office A using this physical cable.

Ok . . . provide a little more detail, please. Are you logged into a pc/server/box on the "office b" lan and you can ping a pc/server/box on the "office a" lan? And when logged into a pc/server/box on the "office a" lan you cannot ping a pc/server/box on the "office b" lan?
Again, if you can ping in one direction, but not the other, there's clearly connectivity and routing that's allowing that to happen. Are you sure the device in "office a" that you are pinging from "office b" does not have a local firewall installed?
