Vodafone 203.97.215.1 gateway server ping is down and I'm client, which means all my web services are down too.

 

 

Anyone else has experienced the problem?

i'd recommend logging a fault if you are having issues.

 

 

 

Testing both my VF connections, all is working well.

still problem for me, tech can't fix it, strange.

 

 

can VF gateway server blocks any coming traffic specifically for my IP(may be ddos attack) for some reasons?

The mention of ddos in your post kinda implys this is what you suspect the cause is?

 

If so , it would not surprise me if your IP got nulled.

 

 

 

I can't speak for VF entirely but this realistically should be indictable by the reps. b

Don't get ping replies from that IP here (outside of Vodafone BB network if that helps?)

 

 

203.97.215.x looks like a cable IP range, so assuming that is the default next hop for your broadband connection? Have you tried restarting the cable modem? Have you changed plans recently, your configuration seems to be for the old DOCSIS 3.0 (non-FibreX) network

OK, looks like its my end, I asked a couple of my friends to test my web services and it works fine, even for me using spark 4g works fine. I rebooted modem/router, helped nothing, any other idea? Why I can't see anything from my house?

Many reasons why the hop might not be responding to ping requests.

 

 

It does not necessarily mean your internet connection is down as you have found out.

Based on this, it definitely seems isolated to just your connection - May be related to simply your node area though..

 

Call vodafone back and log a fault.

Still can't figure out, my modem/router block my IP/domain name for my house? browsing http://203.97.215.XXX is not working, browsing http://mydomain.com is not working, work for everyone else outside my house, how its possible? I used Android native app, iOS native app, win10 firefox/chrome, nothing. If it is my router, I can't even remember when I touched it to change the settings.

Wait... are you saying, you simply can't browse to your own IP address from INSIDE your network?

 

More than likely this is a NAT loopback thing which depends on implantation on routers.

I'm a little but confused as to exactly what you think your issue is. A gateway doesn't need to respond to ICMP requests and it looks like in this case Vodafone have configured their network so it doesn't. This does not mean your internet is down.

 

You won't be able to connect to an internal webserver inside your network using your public IP or domain name unless you router or firewall has been configured for hairpin NAT / NAT loopback. 99% of routers don't support this functionality and it's normally only something you get on a firewall that allows full customisation or allows you to add your own IP tables rules.

Exactly right, or using domain name. But I did no do any changes on my router so long ago so I even remember when last time I touched it. Where this NAT loopback? I can check my router, may be port forwarding, I use a lot of them

It's trivial to block ICMP pings. I block them on my server, because there's no reason to allow them. Actually, I allow them for my IP, but not others, just in case I want to ping it.
