让两个Linux VM互相Ping

Question

我正在将VMWare Workstation 14.1.8与两个Linux VM一起使用：Red Hat 6和Red Hat7。我需要它们能够在Windows 10主机上相互ping通。我都使用自定义特定的虚拟网络（VMNet2（仅限主机）在192.168.116范围内），其IP为：

RH6：192.168.116.128

RH7：192.168.116.129

出于某种原因，RH7可以ping通RH6，但是RH6不能ping通RH7。我感觉我的VMWare设置正确，问题出在RH6网络配置上。我应该在RH6机器上采取什么步骤来修复网络配置，以便ping RH7 VM？

This is what happens when I ping from RH7 to RH6 (success)

And this is what happens when I try to ping from RH6 to RH7

编辑：从RH6添加tcpdump输出。因此，似乎RH6以某种方式看到了RH7，因为00：0c：29：51：10：97是RH7 VM的MAC地址。

RH6的路由表：

Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
192.168.116.0   0.0.0.0         255.255.255.0   U         0 0          0 eth0

虚拟网络编辑器设置：

vmnet2 DHCP设置（两个虚拟机都设置为使用该设置）：

所以我也要早些发布RH7路由表，但它看起来与RH6完全一样：

Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
192.168.116.0   0.0.0.0         255.255.255.0   U         0 0          0 ens37

这是从RH6 ping到RH7 tcpdump的样子：

[root@localhost groberts]# tcpdump -ennqti ens37
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on ens37, link-type EN10MB (Ethernet), capture size 262144 bytes

最终编辑：看来防火墙是罪魁祸首。我运行了“服务防火墙停止”，RH6现在从RH7接收到ping命令：

Answer 1

所以看来防火墙是罪魁祸首。我运行了“服务防火墙停止”，RH6现在从RH7接收到ping。
