Hi, I've been wondering if a dynamic routing solution like babel might help me in this situation.
Havnig two sites, Home (A) and Data Center (B). I rely heavily on IPv6, do as little v4 as possible. So up until today I'm running two static /48 GUA prefixes at both sites. In order to migrate to a faster fiber connection on A I will soon loose my static prefix. I'm running a wireguard tunnel between both sites which currently routes statically. Now my idea was to migrate to ULA at A. The problem with that approach though is that hosts in A will use their GUA address they as a source address, which will result in asymmetric routing. A host will contact B host and return packets will try to run outside the tunnel as there is no route. Rules will prevent that data from arriving, which is of course wanted behaviour. I want to run all the traffic between the sites through tunnel. I though I could use babeld to just fill that gap and always have a route to the prefix I get at home. So even when there is a disconnect and a new prefix, I thought babeld will just fetch it and push it over to site B. Is that a valid idea? If so, what would a configuration will look like? Do I just have to configure the wireguard interface on both sites or will I have to add filters? Thank you!
