我想创建 SIPP 脚本来创建场景，使用以下内容在 UE 和 PCSCF 之间建立 IPSEC 连接；
例如：-
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
已创建 4 SA，我使用 setkey -D 进行了检查。

但是当我从安全 UE 客户端端口向 PCSCF 安全服务器端口发送第二个注册时。它没有发送 ESP 数据包。请帮忙。如果您需要更多信息。我可以提供。
