Wireguard and tailscale

flat4 · Feb 11, 2025, 3:13 PM

Just wanted some feedback not having an issue but was curious.
I recently moved from OpenVPN to wireguard and one of my vlans (20) uses the WG to connect to a vpn provider.
I've known of tailscale for a while but never realize how simple it was to install and configure on my pfsense. So I signed up and on the initial config of tailscale I set 3 vlans to be routed one of them is the vpn (20). Everything seems to work. I have notice everyone in a while when I am using a device on the vpn vlan (20) slows down to a crawl but it recovers. I did set the pfsense box as an exit node.

My questions is, is having vlan (20) in the tailscale routed network causing issues with WG.
Or better yet is tailscale and WG a good thing to run at the same time? Considering I use Tailscale to connect to my network and WG to get out and surf the webs.

Thanks

You could be seeing some conflict there but I would expect a complete loss of connection in most cases if that were happening.

Try disabling one or the other and see what's effected, if anything.
