RTX1100のIPsec設定はこのようになっています。

tunnel select 1
ipsec tunnel 10
ipsec sa policy 10 1 esp aes-cbc sha-hmac
ipsec ike always-on 1 off
ipsec ike encryption 1 aes-cbc
ipsec ike group 1 modp1024
ipsec ike hash 1 sha
ipsec ike keepalive use 1 on
ipsec ike pfs 1 off
ipsec ike pre-shared-key 1 text xxxxxxxxxx
ipsec ike remote address 1 any
ipsec ike remote name 1 yyyyyyyyyy
tunnel enable 1

何か足りないのでしょうか？
