我正在用一台 asa 和两台计算机做一个非常简单的实验室。PC1 连接到 dms PC2 连接到外部

: Hardware:   ASA5506, 4096 MB RAM, CPU Atom C2000 series 1250 MHz, 1 CPU (4 cores)
:
ASA Version 9.6(1)

access-group PING in interface dms
access-group PING out interface dms
access-group PING in interface outside

尝试从 PC1 ping 到防火墙时没有问题。但是我无法从 PC2 ping 到任何地方

YKS(config)# packet-tracer input dms icmp 100.0.10.1 1 2 3 100.10.9.5

Result:
Action: drop

它没有显示任何原因，掉落或其他。据我所知，它应该有理由放弃。就我而言，它只是下降。如何解决此问题？
