Hello,
we are facing a strange issue with Azure virtual network.
This is a subnet settings
ADDRESS SPACE. 10.5.0.0/16
SUBNET A: 10.5.2.0/24
Gateway: 10.5.1.0/24
The Site-to-Site VPN us up and running.
I create a VM that gets the following settings:
Ethernet adapter Local Area Connection:
Connection-specific DNS Suffix . : abcd.a10.internal.cloudapp.net
Link-local IPv6 Address . . . . . : fe80::5094:b9bf:c0ed:6fae%11
IPv4 Address. . . . . . . . . . . : 10.5.2.4
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 10.5.2.1
Link-local IPv6 Address . . . . . : fe80::5094:b9bf:c0ed:6fae%11
IPv4 Address. . . . . . . . . . . : 10.5.2.4
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 10.5.2.1
And now the interesting part begins:
pinging gateway on the other side of the tunnel times out.
tracert 192.168.3.252
Tracing route to 192.168.3.252 over a maximum of 30 hops
1 1 ms 1 ms 1 ms 10.5.1.4. <-- IT reaches the Azure gateway

3 * * * Request timed out.
4 * * * Request timed out.
2 * * * Request timed out. <- And is lost afterwards
3 * * * Request timed out.

There is no traffic coming in from Azure. It feels like it get's blocked by Azure firewall, or the routing is broken -- there is no obvious explanation otherwise.
Thanks,
Andrei
