（前台启动日志卡在这里不动）
后台日志报错如下

192.168.187.102是dsc节点2的私网IP，192.168.187.104是dw备库的私网IP，都可以ping通，只是端口不通，不知道是哪里配置有问题

dmmal.ini参数如下
$ cat /dm8/dsc_config/dsc0_config/dmmal.ini
[mal_inst0]
mal_inst_name = DSC0
mal_host = 192.168.187.101 #私网IP
mal_port = 9340
mal_inst_host = 192.168.100.101 #公网IP
mal_inst_port = 5236
mal_dw_port = 3567
mal_inst_dw_port = 5276

[mal_inst1]
mal_inst_name = DSC1
mal_host = 192.168.187.102
mal_port = 9341
mal_inst_host = 192.168.100.102
mal_inst_port = 5237
mal_dw_port = 3568
mal_inst_dw_port = 5277

[mal_inst2]
mal_inst_name = DW01
mal_host = 192.168.187.104
mal_port = 9342
mal_inst_host = 192.168.100.104
mal_inst_port = 5236
mal_dw_port = 3569
mal_inst_dw_port = 5278

请专家指点下排查思路，谢谢。
