我正在创建SIPp脚本，以创建用于在UE和PCSCF之间建立IPSEC连接的方案。
当我从受保护的UE客户端端口向PCSCF受保护的服务器端口发送第二个寄存器时，它没有以ESP数据包发送。尽管已经创建了SA，并且已经使用setkey -D进行了验证，但是IPSEC并未得到应用。
setkey -c << EOF
spdadd $pcscf/32[$port_pc] $ue/32[$port_us] tcp -P in ipsec esp/transport//require ;
spdadd $pcscf/32[$port_pc] $ue/32[$port_us] udp -P in ipsec esp/transport//require ;
add $pcscf $ue esp $spi_us -m transport -E $ealg $ck -A $alg $ik
EOF
4 SA's has been already created
