📝Publish IP addresses/ranges of edges? #1362

Hi,

I have a working OpenVPN at home via landline ISP that I am happy with. I have setup a backup cellular data USB dongle. While on main link I do have public IP, the cellular performs a NAT so I cannot have a public IP for OpenVPN.

I'm thinking of setting up a cloudflared tunnel to work via the cellular link but I'd like to route only traffic towards cloudflare tunnel edges via the link and maintain the main link as default.

I've looked at https://www.cloudflare.com/ips/ but I am unable to tell which is which - I'd like only traffic destined to tunnel edges to leave via cellular link. Could you help with a list of edges IPs? I'm in Bucharest and I see it picks up 2 OTPx and 2 some other European edges.

I could dns enumerate all OTPxx edges but how is that stable in time, are they fixed or do they change from time to time?

Thanks

hm, can I count on that 198.41.192.0/24 is OTP datacenter and cloudflared will always pick it? because that would also create redundancy if I route 198.41.192.0/24 via my backup cellular link, and the daemon will have two sessions via cellular and two via landline.
