After upgrading libnss-sysytemd library to the latest version 237-3ubuntu10.12, IPSEC/L2TP VPN connection is established but I cannot connect to outside of LAN. I found out the route table was not the same as the version 237-3ubuntu10.11. The difference is the order of the ip addresses. On 237-3ubuntu10.12, the order of the remote vpn ip address on route table is normal order but the VPN connection doesn't work well. On 237-3ubuntu10.11, the order is reverse order, then VPN connection works well.
But today, it happens again on the Starbacks WIFI even on the version 237-3ubuntu10.11. The route table is below.

I'm sure it's a bug of systemd. Has anybody reported this bug yet?
I'm using strongswan and xl2tp. It doesn't cause this problem anyway.

The IP address with reversed ordering of the octets has a trailing dot, which indicates it is the significant part of a reverse DNS PTR record. See :
