Hm, I think in theory you should have the PC in the middle with 2 IP
addresses, on each interface different. On each segment (each side of
the middle one) should be IPs from different range and there should be
allowed routing (that I do not know how). It would look like this:

-->( PC1 <IP-A/Range1> ) -- ( <IP-B/Range1> PC2 <IP-C/Range2> ) -- ( <IP-D/Range2> PC3 )

PC2 can comm with all (since it is on both nets). PC3 shloud use IP-C as
its gateway, which will allow it to access PC1. PC1 should have static
route for whole Range2 to IP-B, so it can send to PC3. Now, how is that
set in Windows, who knows..

After this all is set, PC1 and PC3 should be able to talk to each other.
However, you will not see the pings unless both directions work.

So, you need to:
• PC3: /etc/conf.d/net:routes_eth0 = { default via IP-C }
• PC2: enable routing (I guess /etc/conf.d/net too)
• PC1: add a static route Range2 -> IP-B.

I just hope I did not mess that up.

Or you can set up a bridge on PC2 to make both segments one net only:

Have a nice day
