ipsec

I'm working with a client who wants to set up a vpn tunnel between their network and ours. They're in charge of the tunnel and to give us the access they are asking me my public IP and my LAN IP.

This is what i've got when i do an ifconfig on the server i will use to connect to the vpn

$ ifconfig
eth0      Link encap:Ethernet  HWaddr d4:ae:52:cd:xx:xx  
          inet adr:62.210.xxx.xxx  Bcast:62.210.xxx.xxx  Masque:255.255.255.0
          adr inet6: fe80::d6ae:52ff:xxxx:xx/64 Scope:Lien
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

          Interruption:16 Mémoire:c0000000-c0012800 

lo        Link encap:Boucle locale  
          inet adr:127.0.0.1  Masque:255.0.0.0
          adr inet6: ::1/128 Scope:Hôte
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          Packets reçus:45923382 erreurs:0 :0 overruns:0 frame:0
          TX packets:45923382 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 lg file transmission:0

The inet adr:62.210.xxx.xxx is my public IP but it seems like i dont have any LAN IP.

Can the connection work without LAN IP or should I create a private network somehow?
