Azure vWan Hub routing between regions

Darren Mitchell 0

Hello,

We are having issues with Azure Routing, and we cannot get around this.

We have a DC in an identity network on our vWAN Hub on our North Europe Hub.

This is unable to communicate with our UK South DC on the same vWAN.

All other vms are in place and routing is fine for these vms.

Thanks

Thanks for getting back to me.

so this turned out to be a firewall setting in hubs for hun to hub communication needed to be enabled.

We have have issues with a new vwan vpn gateway. We have site to site connectivity but no traffic is passing.

Firewall looks fine so not sure what else

Any ideas

Hello Darren Mitchell,

Please confirm that the site-to-site link and on-premises address space are correctly configured.

Check whether the Azure parameters from both on-premises and site-to-site are the same.

Check the Tracert from on-premises to Azure IP Address to determine the exact issue.

Please let me know if you are still facing any issues.

Ganesh

Hello ,

I have checked the 3 things you mentioned and they all check out.This is the setup of the vWAN

We have rules in the firewall to allow the traffic on the S-2-S to access the network etc.

We are at a bit of a loss at the moment.

Thanks for your your guidance so far.

Hi Darren Mitchell,

Good day!

Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.

It sounds like you're dealing with a challenging Azure Virtual WAN (vWAN) routing issue.

Please check the Routes Propagation from the Azure portal; whether it is propagated or not, this can be seen in vhub.

If you have any further concerns, please do not hesitate to contact us. We are pleased to help you.

I'm looking forward to your response and appreciate your time on this.
