Split Tunnel by Domain on Router Level? (lemmy.ml)

Running pfsense, I was able to route my entire LAN subnet through a VPN. I have firewall and NAT rules that use an alias to filter outgoing connections to specific domains outside of the VPN gateway.

This works great. But here's the problem. Wildcards are not supported within pfsense aliases, and therefore unless you know the specific subdomain for a service, there's no way to reroute services that use rotating or load balancing subdomains.

Surely this is a big problem in large companies. I'm sure they utilize a paid solution to solve this problem.

Are there any solutions for self hosting that are FOSS or within pfsense?

What exactly are you trying to split out? Generally, routing is done at the IP level, not by name.
