Let me know what you guys think.

I have VPN client access via 5520's

Latest Cisco VPN Clients

Normally, they connect via their home/isp, establish VPN, and able to connect to my server subnet 192.168.1.x

There are a few places where their ISP, gives them a local dhcp address of 192.168.1.x. My client connects to VPN, can get to anywhere on my internal network, EXCEPT for the 192.168.1.x server subnet.

Shouldn't the VPN client firewall/nat all traffic to VPN yes? Why wouldn't it here in this location.

As a temp fix, i had to remove the local route, and added a temp to hit my core routers.

The Support for Dynamic DNS (DDNS hostname population) sends the VPN Client sends its hostname to the VPN device when the connection is established. If this occurs, the VPN device can send the hostname in a DHCP request. This causes the DNS server to update its database to include the new hostname and VPN Client address
