I assume you mean 2.4.5, since 2.4.7 is the latest stable version.

I see what is going on now, they are assigning you an address pool,
That's what the 3rd set of private addresses is for.
Do you know what vpn software the other side is using?
You should use left=220.127.116.11 or your public ip if that isn't it.
If the other side doesn't like it they need to change their settings to match.
You will also need to setup a NAT to convert your private lan traffic
172.18.112.0/20 To 172.25.8.8/29 before it is sent to 172.20.210.48/29.
I've never actually got this to work myself, but I'd imagine it could be done
By: iptables -t nat -A PREROUTING -s 172.18.112.0/20 -d 172.20.210.48/29 -j SNAT --to 172.25.8.9-172.25.8.14
