Hi,

I am having issues with the Azure VPN connection to our IFS Cloud build place.  I can connect successfully, but the DB host name resolution does not work.  For example, we are given this DB host for our buildplace:

myhost-dev2-db.build.ifs.cloud:1521/alepdb

I cannot connect using this host name, and I can’t even ping that host.  If I use the database’s IP (10.37.x.x), I can connect and query the DB normally.  This is fine as a workaround, but the IP can change.

Is there a DNS server that can be manually added to my Azure VPN profile?

Thanks

@SAARBISHOP The IPs generally do not change a lot so its quite a stable solution. 

The fact the DNS resolution does not work is mainly due to how your computer is setup to do do the DNS resolution. 

Mostly if you have other VPNs running at the same time (enterprise VPN / Tailscale) they could interfere with the DNS resolution. 

So maybe make sure you only have one VPN running and then the DNS resolution should work correctly. 

According this post you could try to set your own DNS but not sure if that will help you

 

 



 

 

I added 8.8.8.8 and 1.1.1.1 as name servers for the Azure VPN adapter and reconnected and the name resolution still failed.  

Hi Ryan,

The above Google and Cloudflare name servers only resolve publicly resolvable addresses.
10.37.x.x is an internal IP address block that neither Google or Cloudflare know about.

Perhaps that DNS assigned when connecting to the Azure VPN is being overwritten by something in your environment.
Please check which name server is being used when you try to resolve the hostname.
If on Windows you can try "nslookup <hostname>". On Linux "dig <hostname>".
Please check with your network administrator whether anything can be done to restore the VPN DNS servers.

Best regards -- Ben
