I have 2 sites
My home in Austin TX and an Apartment in the Philippines.
I want to have a site to site connection
My home in Austin TX.
UDM pro connected to Spectrum ISP cable modem, bridged… UDM pro is setup with DDNS for ipv4. ipv6 is configured and working.
My apartment in the Philippines.
ISP supplied fiber device, has 4 ethernet ports and wifi. The device is essentially equivalent to a consumer grade wifi router with a web ui. The WAN side does not have a public ipv4 address, the ISP does not offer a public ipv4. ipv6 is not offered.
I am bringing an old Netgate SG-2440 running pf-sense+ 23.05
I have a free tier cloudflair zero trust teams account. I don’t currently don’t have a tailscale account
Since I don’t have a public ipv4 address in the PI apartment, can I setup a reliable site to site VPN if the pfsense device would have a non-public WAN ip address?
Would an overlay, like cloudflair tunnel or tailscale be a more reliable option?
