rule 0 permit ip source 192.168.1.0 0.0.0.255 destination 192.168.2.0 0.0.0.255 (4 times matched) rule 0 permit ip source 192.168.2.0 0.0.0.255 destination 192.168.1.0 0.0.0.255 (14 times matched)
看你的感兴趣是Flow: sour addr: 192.168.1.0/255.255.255.0 port: 0 protocol: ip dest addr: 192.168.2.0/255.255.255.0
看看acl与nat拒绝的acl写的对不对

没写拒绝的就写了通过的
rule 0 permit ip source 192.168.1.0 0.0.0.255 destination 192.168.2.0 0.0.0.255 (4 times matched) rule 0 permit ip source 192.168.2.0 0.0.0.255 destination 192.168.1.0 0.0.0.255 (14 times matched)
