The config I had auto-migrated to V7 and worked.
However, now that I come to make changes, I see some unfamiliar things, and don't readily find the answers in the help website.
First question: I have a VPN (was PPP, now Wireguard Traffic fro specific IPs is marked and directed to this interface. When I look at the route info I see the destination address specified as 0.0.0.0/0^1024 -- what is the ^1024 ???
Second question: Routing for the Internet connection doesn't appear to have changed, because it was based upon IP addresses. However, other routes, to interfaces, such as the one mentioned above now have the same interface names, but proceeded by a '%' character. E.g. %wireguard1 What is he significance of the '%'? is it required?
