Hi,
I have configured a Site-to-site virtual network in order to connect our Azure VMs with our partner's on-premise network that hosts some services we need to access.
The virtual network seems to be ok... everything looks ok in the Azure portal and I was able to create a VM in that network without any issues.
I can even ping the on-premises server from the VM with no problem.... The problem is that I cannot access the web services that're hosted in this on-premise server.... I just try to access it by using the URL (using port 8085) and I just get a timeout.
I've configured the VM's firewall with an outbound rule on port 8085.... and I have requested our partner to ensure the port 8085 is accessible from our virtual network private ip range. They have confirmed the port is open as they have even created a loopback in the VPN device to test whether incoming connections from our IP address are allowed.
So, right now, I'd like to know:
1. What can be happening here? What else should I look at?
2. What can I do to diagnose these connectivity issues? How can I find where's the problem now?
3. Why can I ping the remote on-premises server but when I try to telnet on port 8085 it doesn't work (and the remote 8085 port is open)?
I'd really appreciate any help on this issue!
Thanks,
Rodrigo.
