I have an expanding homelab that is now including a family members home. I have homeA.com, and they have homeB.com. I manage both, and connect to theirs over Tailscale. Both servers run pihole and traefik. What I want, is to be able to connect to homeB.com from homeA.com. I have a DNS entry in homeA pihole for homeB.com=100.x.x.x (Tailscale ip). So, any device on Tailscale and homeA pihole can access homeB.com.
What I would like, is to make it so only the two servers need Tailscale. So on my laptop, without Tailscale, from homeA, can access homeB.com through the servers Tailscale connection. Is this possible?

This is what is called a site to site VPN connection. Id suggest just using wireguard without tailscale given the amount of set up you need is minimal. A typical pattern is to connect a site to site von on each router of the given network you want to connect. Lots of router software support wireguard nowadays so depending on the software you may just be able to search for your router software + site to site VPN configuration.
That being said tailscale also has docs on this: tailscale.com/kb/1214/site-to-site
The routers or computers you are using for this have to support forwarding traffic. With Linux this is pretty straight forward for other OSes I’m not sure how easy it is.

You can get around this by having tailscale installed on the default gateway (router) of each network. It might be quite a pain for OP to change routers at each location. On the plus side, OpenWRT has some other cool features like PXE booting.
Here is an article about tailscale on an OpenWRT router.
