FQDN L2TP server address is only resolved at boot
Im using "russian vpn" scheme to connect with ISP - WAN interface with DHCP (actually internal ISP network) + L2TP interface to ISP server (as real WAN). If im using FQDN as L2TP server name - it couldn't be resolved during boot up, so i have start this interface manually. Even if i put static DNS entry for this server name to DNS resolver - its still couldn`t be resolver during boot. If i use ip as server address - everything is ok and L2TP interface going up automatically during boot.
Could someone fix this problem, because ISP balancing load between L2tp servers and returns different ip for same FQDN..
