Tailscale version: 1.28.0
Your operating system & version: Ubuntu 20.04, but this question is for any OS
Hi!
I’m rolling out Tailscale across a few locations, some of which are in the cloud. One of these locations has 5 VMs that all have public IPs and internal IPs using a WAN and LAN approach. Tailscale connects just fine, and all are reachable through the tailscale-generated IP address.
However, I’d like to keep the existing internal IPs available and reachable throughout the rest of the network. Some services rely on those internal IPs. Right now, it’s connected via a traditional VPN.
The only way I’ve found is to mark them as a subnet host and use i.e. ---advertise-subnet 10.10.0.10/32 - which is not good for my subnet host quota. 
TLDR: is there a way to have tailscale advertise the LAN IPs?
Thanks!
