Issue to reach specific VPN service - IP unreacheable
vor 16 Tagen
Hello,
I'm facing issues to reach a certain corporate VPN server (hosted in South America).
As I'm able to resolve its hostname, I tried do trace my route to the final IP. While doing it, my connection manages to do a few jumps but get stuck after reaching the first IP in the destination country.
Is there a way to check if a certain IP is somehow blocked? I have some colleagues in Germany and others EU countries that can reach the server without any trouble.
Additional information:
- I tried to use my partner mobile network (O2) and, while it uses a different route, it also stops on the very same IP / location;
- I can use other VPN servers hosted in the respective country.
I'm running out of ideas to test together with the respective IT team.
Thanks in advance.
Best regards,
Lucas

Hi Lucas @user_e16b06,
that sounds like an issue with the VPN . I doubt that we can help you with that.
Could you provide us with a traceroute?

That seems like a routing issue within the local ISP .
When you resolve the hostname for the VPN gateway, do you get an IPv4 or an IPv6 address?
In case of the latter, it might be worth trying again with IPv6 disabled on your device.

@user_e16b06 : I assume that you are using traceroute/tracert to determine the route. This involves sending ICMP echo requests. Not all routers answer ICMP packets. Either because they are blocked or the router is overloaded. Other IP packets can usually pass if there is no congestion. Since both Telekom and O2 are stuck in the same place, the problem is definitely not a Telekom problem. And there is nothing you can do about it.
