Remote VPN not goes thru tunnel

Hello all,

My company is running remote VPN for HQ site. VPN is running fine.

But now company expand one more branch, it connects to HQ by a physical layer 3 link.

HQ site is assigned IP range of 10.192.0.0/16 by a DHCP server 1

Branch is assigned range of 10.64.0.0/16 by a DHCP server 2.

Two system are separated system (not same DHCP, DNS, internet ,....), only connect via physical link as I mentioned.

Topology I attached.

My proplem is remote user can not reach branch site. When they tracert to an IP on branch site, it even go thru internet instead of go to VPN tunnel.

Please help find root cause?

Thanks you!!!

Did you include this address space in the relevant RemoteAccess encryption domain?

Thank you; I found that I have not yet included branch prefix in VPN domain (Network Management > VPN domain > then add more prefix)

Now it works.
