I just got a wired problem this morning, and I hope someone can explain it.
I connected the router to the internet,this router obtained a static ip address via PPPOA from ISP. And I was on internet...
BUT there was some sites I could not open at all, so I tried open them using clean ip address instead of the domain name just for to be sure that dns is not causing any problems, but NO. See the example below, I will use example ip addresses:
220.127.116.11 I can reach the web side using this ip, and I also got a ping from this ip
18.104.22.168 I can`t reach this ip and I can`t get the ping response from it either,
but I can reach this ip via another isp provider...
remember I used just example ip addresses instead of real ip, but as you see both of these 2 ip addresses are the same subnet, so "call it rouring problem" would be wrong since these 2 ip addresses are on the same subnet.
I just don`t understand what is the problem here.
There are no ACL`s no firewalling at all ! Everything is opened.
Any idea ??
