I am able to establish IPSEC connection between one client per server. Actually I can connect multi Ipsec server at the same time. But I have realized that when servers have same xl2tpd.conf file like following
[global] ipsec saref = yes listen-addr = 18.104.22.168 [lns default] ip range = 192.168.1.10-192.168.1.20 local ip = 192.168.1.1 ;require chap = yes refuse chap = yes refuse pap = yes require authentication = yes ppp debug = yes pppoptfile = /etc/ppp/options.xl2tpd length bit = yes
Server 1 can be reachable via 192.168.1.1 ip address however Server 2 can be reachable via different one assigned randomly say 162.xx.xx.xx though in xl2tpd.conf->local ip is set 192.168.1.1. Actually I am not expecting to reach diffent machines with same ip address. But how can I make server unique by modifiying the xl2tpd.conf files of all servers.
