Linux 和 Windows 客户端运行良好。例如，我可以看到从客户端到服务器的 ping，如下所示：
19:50:18.075816 IP me.59547 > server.4500: UDP-encap: ESP(spi=0xcbb1e4ea,seq=0x32b), length 132
19:50:18.076105 IP server.4500 > me.59547: UDP-encap: ESP(spi=0xc14e4d72,seq=0x329), length 132
隧道状态：
ikev2-pubkey[439]: ESTABLISHED 26 minutes ago, 100.200.100.200[mydnsnmae.com]...150.160.150.160[me]
ikev2-pubkey{331}: INSTALLED, TUNNEL, reqid 177, ESP in UDP SPIs: cbb1e4ea_i c14e4d72_o
ikev2-pubkey{331}: 10.0.0.0/16 === 10.10.0.1/32
但是对于 macOS (Catalina)，事情就另当别论了。我已成功建立连接：
ikev2-pubkey[442]: ESTABLISHED 7 minutes ago, 100.200.100.200[mydnsnmae.com]...130.120.130.120[me-mac]

ikev2-pubkey{334}: 10.0.0.0/16 === 10.10.0.4/32
并且只看到一种方式的数据包：
20:01:27.933739 IP 150.160.150.160 > 100.200.100.200: ESP(spi=0xc632be22,seq=0x5f), length 392

我看到和之间的区别ESP in UDP SPIs:，ESP SPIs:但不明白它的含义。
我应该检查什么才能使 macOS VPN 客户端正常工作？
