UTM VPN Client Can't Access Site to Site VPN

This question has already been asked a lot and user Balfson has written a nice knowledge base article here.

In Remote Access>SSL profile the local network has the subnet of Site B.

I have ran tracert on a laptop with the VPN client and it seem to complete but through the external route. 10.1.0.6 is a server in MS Azure.

below are the results.

Did you also configure the VPN-ip pool inside the tunnel between site A and site B?

I can't follow your ip-subnets. In your first post you say internal is 192.168.1.0/24 and remote is 10.0.0.0/24 and IP pool is 10.30.10.0/24 (is this a VPN pool and if so which one?) 

Also your tracert shows 172.16.1.1 as a first gateway.

If my first question up here doesn't solve your problem, then please add a drawing of your network layout including the subnets.

Apologies for the confusion, the ip-subnets are examples only.

I configured the Virtual IP Pool in Remote Access>SSL>Settings, I have also put the VPN-IP Pool in site-to-site VPN>Connections (local networks).

The VPN pool should also be in site B's config as a remote subnet....

That did the trick, I completely forgot to check the remote side.

Thank you.
