Forwarding HTTP access to a third-party host at the end of the IPsec tunnel, how to do it?

Question

Computer networks

Hello, help pzhl
The situation is as follows.
DMVPN and many branches (BRUNCH). There is an Ipsec tunnel at the other end of 10.23.10.7 where the site is. Only 192.168.0.5 and the DNS server have access, but when the call goes through port 80, it opens the IIS 10.23.10.7 page, but when you write this address in the hosts name.site file, everything opens perfectly. But the issue is access for BRUNCH hosts on name.site (10.23.10.7).
If you just set up forwarding on port 80, then it opens the IIS page, at least write anything in Hosts.
Please give me advice on how to solve this? can reconfigure the internal DNS ku like that?? Or are there any programs for this?
I will be grateful.
PS: I temporarily solved the issue by remoteApplication, that is, BRANCHs enter the remote browser on the server 192.168.0.5.
